Teco Medium Voltage Solid State Starters, 2,300-6,900 Volts TEAMmaster

Protect your machinery investment with our medium voltage soft starter!

Protect your machinery by controlling motor torque, reducing current demand and creating more stable voltage!
 
Great option for municipalities.
 
 
 

Today’s global economy is in many ways driven by AC induction motors. Industrial facilities worldwide depend on these motors to drive the machinery that enhances their efficiency and increases their production output.

However, many industrial operations unknowingly subject their machinery to severe stress during motor start-up. When motor operation is activated, high inrush currents flow into the motor’s windings, producing very high levels of torque.

This torque at the motor’s shaft can result in a substantial shock to the driven equipment. The result may be belts slipping or breaking, couplings disengaging, and gears or other components failing completely.

Therefore, it is often a cost-effective decision to protect your machinery investment with a TEAMmaster™ medium voltage soft starter. Available only from TECO-Westinghouse Motor Company, the TEAMmaster™ protects your machinery by controlling motor torque.

The TEAMmaster™ also reduces current demand and creates a more stable line voltage, which benefits facilities that have weak electrical systems.

 

The TEAMmaster™ Medium Voltage Starter is a microprocessor controlled solid state reduced voltage starter for three phase induction motors. The starter provides a closed-loop current ramp for smooth step less motor acceleration, supplied in a free standing enclosure.

Enclosures are available in NEMA 12 or NEMA 3R configurations. The medium voltage enclosure consists of two distinct compartments: The medium voltage or power pole section is located in the main body of the enclosure, whereas the low voltage section containing the control logic is located behind the door as an isolated compartment.

Each starter is supplied with a load break isolation switch, Class “R” motor fuses, inline vacuum contactor, solid state power poles, and a vacuum bypass contactor. This bypass connector is used to bypass the SCR power poles once the motor is up to full speed.

The logic control incorporates the MX3 computer that has all the circuitry required to drive the power semiconductors, which are located in the power section.

TEAMmaster™ starters provide solid state reduced voltage starting for normal operation and full voltage emergency back-up starting, with complete electronic motor protection at the flip of a switch.

This unique redundant design is ideal for critical applications where downtime is extremely disruptive and cannot be tolerated. MX3 solid state controls profile precise digital starting and stopping, motor protection, metering, diagnostics and communications... standard.

TEAMmaster™ medium voltage soft starters provide several advantages including:

Protection of machinery from failure and excessive maintenance caused by mechanical shock during starting or stopping. The TEAMmaster™ provides smooth, step less acceleration and controlled deceleration.

Control of the current ramp during start-up. The TEAMmaster™ protects electrical systems from disruptive voltage drops and power outages caused by motor locked rotor inrush current.

Complete line monitoring, motor control and protection. These functions protect mission-critical motors from failure or unscheduled outages caused by machine or electrical system faults.

Programming capabilities. The TEAMmaster™ includes control and power electronics, as well as bypass and isolation contactors that reduce maintenance and operating costs. A UL listing and a CSA approval.

Pfannenberg's Outdoor Side Mount Cooling Units, NEMA 3R/4

The wide condenser fin spacing filter-free design reduces the amount of maintenance required by the customer. A quick cleaning of the condenser is required less frequently verses the competition's models, while capacity is not compromised by easy clogging of the condenser core.

Utilizing rugged, long-lasting backward curved impeller fans, the cooling units can go twice as long before needing service verses a typical blower style fan that has smaller, low-cost and high maintenance bearings.

The backward curve fan also has a natural right angle air path that allows cooling units to capture hot air from the top of the electrical cabinet and deposit cool, dry air to the bottom of the cabinet and underneath critical components on the panel.

Utilizing a maintenance free design, Pfannenberg implements a hermetically sealed design that eliminates gasketed valves and the leak source for many other A/C unit designs. Therefore, these cooling units do not need annual maintenance to determine if the unit is properly charged with R134a refrigerant.

Controlling temperature and alarm setting via dip-switches, preventing airflow short cycling, high pressure switch alarm, on/off control of compressor with built-in delay timer and a LED lamp with four different flashing sequences. The control board is located in inner air circuit for protection from heat and dirt.

Pfannenberg strives to provide a relatively maintenance-free design. All designs have additional options including:
Filter Kits Option - for special applications like dogwood seeds or desert sand that need an external filter to prevent clogging of the condenser core.
Enclosure Heater Option - for special applications where heating is required to control condensate or keep electronics above a desired temperature range in cold climates.
Voltage Options - Many of our cooling units have been designed for both 50/60 Hz applications as well as 400 or 460 V operations with a simple jumper change in the e-box.

Think Spring AGAIN- ARE ALL OF YOUR PROJECTS COVERED- WHAT IS YOUR APPLICATION- AC DRIVES

All About AC Drives

Variable frequency drives are also known as variable speed drives, VFD's, inverters, adjustable frequency drives, motor controllers, AC drives and microdrives.

Variable frequency drives (VFD's) adjust your motor speed to closely match output requirements, typically resulting in energy savings of 10 to 50 percent.

Variable frequency drives save energy. One way they do this is by reducing motor speed as demand decreases.

Are you looking for a drive to run your three phase motor on single phase power? Our TECO EV/JNEV Series is our most popular single phase input AC drive. This is the ideal drive for hobbyists because it is low cost, readily available from stock and easy to use!

If you require a NEMA 1, general purpose drive then we would recommend our AC Tech Lenze SMVector series. Loaded with features yet still competitive, we can ship from stock today!

Read a great article by Tom Robbins of AC Tech Lenze, "Motor Drive Upgrades Boost Industrial Plant Performance" - discussing the value of upgraded motor controls and variable frequency drives (VFD) over conventional fixed-speed motor drives.

Frequently Asked Questions Regarding Variable Frequency Drives:

Can I use a single phase motor with your variable speed drives?

No. All variable frequency drives work with 3 phase motors only. Single phase drives will operate on single phase power, however, the output is still 3-phase and will require a 3-phase motor.

How do I choose the proper size variable frequency drive (VFD)?

For most applications you want a variable frequency drive that has an output rating that equals or exceeds the nameplate current rating of the motor. If you base your selection on the motor horsepower rating you might get a VFD that is too small. For severe or unique applications please contact our in-house technical department.

How will using a variable frequency drive (VFD) save me money?

If you have an AC motor drive application that does not need to always run at full speed then you can reduce energy costs by controlling the motor with a variable frequency drive. VFD's allow you to match the speed of the motor to the requirements of your process. Basically variable speed drives allow you to consume less energy when your load requirements are less than full speed. Ideal in HVAC applications.

Variable speed drives also gradually ramp the motor up to operating speed which avoids abruptly starting the motor. This will reduce the stress on the motor and extend the life of the driven equipment and motor.

MTE RL Line-Load Reactors - Help minimize line and load harmonics

MTE line & load reactors help keep your equipment running longer by absorbing many of the power line disturbances which otherwise damage or shut down your inverters, variable frequency drives (VFDs), variable speed controllers, or other sensitive equipment.

HARMONIC COMPENSATION makes MTE reactors suitable for use on either the drive input or drive output. They are designed to carry full rated fundamental current and will also handle current and frequencies associated with harmonics up to 50% over the fundamental. This robust design allows all MTE reactors to be used on the output of variable frequency drives including IGBT types with switching frequencies up to 20kHz. A premium dielectric system is designed to protect the reactor’s coils from the potentially high peak voltages and fast dV/dT which may be experienced when used for motor protection with long leads between inverter and motor.

They are a robust filtering solution for virtually any 6 pulse rectifier or power conversion unit. There is no need to de-rate MTE RL reactors as they are harmonic compensated and IGBT protected to assure optimum performance in the presence of harmonics, and are very effective at reducing harmonics produced by inverters and drives. Standard MTE RL reactors may be applied up to 690 VAC with compatible impedance ratings.

HIGH SATURATION CURRENT RATING of MTE reactors maximizes their surge current protection capability. MTE reactors absorb many of the power line disturbances which cause nuisance trips on voltage source units.

3% impedance reactors are typically sufficient to absorb power line spikes and motor current surges. They will prevent nuisance tripping of drives or circuit breakers in most applications.

5% impedance reactors are best for reducing harmonic currents and frequencies. Use them when you must comply with IEEE 519 to reduce motor operating temperature, or to reduce motor noise.
