Let's start with what variable frequency drives are used for...
Variable frequency drives are used for electronic speed control of AC induction motors. You might also refer to them as adjustable speed drives, variable speed drives, AC drives, microdrives or inverters.

The second question is who should be using variable frequency drives?
Marshall Wolf Automation can make this easy to determine by asking you the following questions:

  • Do you have AC industrial electric motors in your facility?
  • Are you looking to lengthen the life of these motors by running them at speeds that are designed for variable loads?
  • Are you trying to save on energy costs? 

If you said yes to the above questions then you should install variable frequency drives on your AC induction motors. 

 

Variable speed AC drives save energy costs, extend the life of your motor and take the burden off other power components. Many utilities are even offering rebates for using variable frequency drives.

Would you like assistance in finding out which of our high performance AC
 drives would be best for your application? As always we offer free in-house technical support.

TECO N3 Series Variable Speed Drives Now Have BACnet Protocol As Standard!

Friday, January 20, 2012 by Beckie Bordenaro
The TECO N3 series now has BACnet Communications included as a standard feature.

teco n3 variable frequency drivesBACnet can be selected via parameter configuration. Then, with optional SIF-485 connector module, the TECO N3 drive will communicate on a BACnet network.

This gives you an excellent solution compared to other available methods of communications, including Gateway modules or 3rd party communication cards.

Gateways have typically been separate cards or mounted devices that are 'translators' from another protocol (Modbus for example) to BACnet. The TECO N3 model can eliminate this added step.

What is BACnet? It is a communication protocol that experienced significant growth in the past few years. BACnet is designed for Building Management Systems which include HVAC but includes other applications as well. These include energy management solutions, lighting, fire prevention and security access.

BLDC Motors

Wednesday, October 12, 2011 by Caryl Clement
BLDC MotorWhat is a BLDC motor?  That's the first thing I thought when I first saw this term.  BLDC means brushless DC motor.  And why is that a good thing?  Because brushes wear out, for one thing.  Also, brushes limit how many poles the armature can have, limit the max speed of the motor, and when the brushes make and break electrical connections, spark and give you noise. 

The only disadvantage of a brushless motor is its higher initial cost, but you can often recover that cost through the greater efficiency over the life of the motor.  That disadvantage disappears if you shop through Marshall Wolf Automation, your industrial automation distributor!  

Our BLDC motors from SPG, available from 10 to 90 watt output power, are a complete package at low pricing!  Our tech support department can cross reference Oriental motors for you and the gearhead is included.  Call us today at 800-325-9653!

WEG Service Tip: Replacing Your DC Motor? Think AC!

Friday, September 30, 2011 by Beckie Bordenaro
I received my WEG newsletter this morning and thought their service tip was worth sharing:

'Alternating-current (AC) and direct-current (DC) motors have traditionally served distinctly different application due to their construction and inherent operating characteristics. 

In general, AC motors were smaller, less expensive, lighter and more rugged than DC motors. DC motors, on the other hand, operated better in variable-speed application, particularly those requiring wide speed ranges, and provided more precise speed control.

DC motors have been the workhorse of industry in many applications where variable-speed operation is needed. In these applications DC motors are reliable and provide precise speed control under variable operating conditions.

The downside is DC motors are expensive to purchase and to maintain. In addition, over the past 10 years, AC drives have improved to the point where their speed control is far more precise, rivaling that of servo drives. What's more, the AC motor and drive together often cost about the same price as the DC motor alone.

The development of modern AC motors and drives is blurring the distinctions that once governed the choice between AC and DC drives. The result is that lower-cost, more-reliable AC drives are moving into application once reserved for DC drives
