- Maximum recommended rotor speed: 6500 RPM at 72V unloaded
- Voltage: 0 to 72 VDC input to the control 
- Torque constant of 0.12 Nm per Amp
- The inductance phase to phase is 0.05 milli-Henry
- Armature Inertia: 45 kg cm² 
- Current: 125 Amps AC continuous (180 Amps DC into the motor control)
- Peak current: 420 Amps AC for 1 minute (600 Amps DC into the motor control) 
- Weight: 36.3 pounds
- Peak Stall Torque: 60 ft lb.
- Cooling: Air cooled (cast aluminum heat sink)
- Includes temperature sensor

Controller Specifications

The Gen4-series represent the absolute latest design concept for compact and reliable AC Controllers. They feature the smallest footprint in the industry for their power capability. The high efficiency of these controller makes it possible to integrate them into very tight spaces without sacrificing performance. The design has been optimized for the lowest possible cost while maintaining superior reliability in the most demanding applications.

The Gen4 controllers are designed to control either AC Asynchronous motors or PMAC Synchronous motors. This feature allows users to select optimal motor solutions for any application. Both UVW and encoder AB inputs are provided for maximum flexibility.
