ACCU-Torq® Motors Vector Duty Induction Motors
Product Overview and Options
Encoder-equipped ACCU-Torq® motors are a low-cost, error-• Class F Insulation
free solution to applications requiring accurate positioning • F-1 Standard, field convertible to F-2 for 180 frame and above or precise speed control without the rapid acceleration
• Normally closed thermostats standard dynamics of a servomotor. ACCU-Torq is designed to be
• Shaft grounding ring option on all ratings used with inverter and vector drive applications requiring up • Encoder and brake provision on all ratings to a 2000:1 constant torque speed range and is the perfect • Three year limited warranty* complement to Commander SL, SK or Unidrive SP drives.
Point-to-point indexing and material handling applications are ideal for ACCU-Torq’s capabilities. Cost savings are significant due to the lower cost of materials used in induction motor design.
Product Features:
• Constant torque operation; zero to base speed on vector drives
• Constant power (HP) operation to twice base speed
• Continuous duty at 40°C Ambient
• Optimized for operation with IGBT and intelligent power module drives (NEMA®† Design A) ACCU-Torq® Motor
