Take a look at our industrial electric motor options!
'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.'
