The merits of new-technology large motors
Technical advances give Large Brushless Drive Systems significant advantages over conventional DC or AC induction motors, as Ed Lee describes in this article
Shaft mount provides the stiffest-possible machine mounting.
The motor has peak torque output of 2685 lb-ft (3640 Nm) and a continuous RMS torque rating of 264 lb-ft (358 Nm) in the Totally Enclosed configuration that is standard.
Special cooling provisions can be made to increase the continuous RMS rating.
Rotor inertia is 0.1757 lb-ft-sec2 providing a maximum acceleration rate of 12 thousand radians per second squared! The motor comes standard with a Heidenhain sinusoidal encoder, providing the equivalent of more than 1 million ppr effective resolution.
The motor can be provided for any available voltage from 160 vdc bus to 700 vdc bus.
Powertec also can provide the Flexmax Brushless drive to run the motor.
This is a high performance brushless drive available up to 400 hp and will run with sinusoidal encoders, digital encoders, hall devices, or resolvers for feedback.
