ACCU-Torq™ Motor Series

Designed for use with inverter and vector drive applications requiring up to a 2000:1 constant torque speed range. This makes it perfect for use with Commander SL, SK or Unidrive SP drives. The ACCU-Torq motor may be used for almost any AC drive application from a simple conveyor to those applications requiring the very best speed and torque or position control. 

Applications

ACCU-Torq™ is ideal for a wide range of applications, including:

  • Winders
  • Material handling
  • Packaging machines
  • Test equipment and otehr idustrial equipment

Benefits

  • Overcomes high load inertia mismatches with use of larger AC motors without the expense of large servomotors and/or gear reducers
  • Provides precise high-speed positioning when rapid accel/decel rates are not required
  • Enables low-cost, error-free closed loop performance in applications that would be cost prohibitive where traditional servo systems are used
  • Eliminates environmental and maintenance issues associated with hydraulic and pneumatic systems
  • High performance 2000 to 1 speed range
  • Encoder ready with cables
  • Constant torque operation from Zero to base speed with vector drives
  • Constant hp operation to twice base speed
  • Optimized for operation with IGBT and intelligentpower- module drives (NEMA Design-A)
  • Class F insulation
  • Normally closed thermostats standard
  • Shaft grounding ring option on all ratings
  • F-1 standard, field convertible to F-2 for 180 frame and above
  • Encoder and brake provision on all ratings
  • Three year warranty

If you need to accurately position the motor, but don’t require the high speed and rapid acceleration dynamics of a servo motor, the Unidrive SP with an encoderequipped AC induction motor may be the optimum performance solution as well as very affordable.

The flexibility and high performance of the Unidrive SP make it possible to control three phase induction motors on applications that previously demanded higher priced servo motors. Point to point indexing and material handling applications are ideal for utilizing this capability, especially when motors above 5 hp are required. The cost savings is significant due to the lower cost of materials used in the induction motor design.

AC induction motors have rotors with more mass and larger diameters than servo motors of the same torque capacity, and therefore higher inertia. This is helpful for high load-to-motor inertia ratios, and in most cases can eliminate the need for inertia matching gear reduction. The higher inertia of these systems also results in greater low-speed stability.
