PrimoPal’s PHSM series hybrid servo motors offer an alternative for applications requiring high performance and high reliability when the servo system is the only choice, while it remains cost-effective. The internal encoder is used to close the position, velocity and current loops in real time, just like the servo system. It combines the best of servo and stepper motor technologies, and delivers unique capabilities and enhancements over both, while at a fraction of the cost of a servo system. The PHSM series hybrid servo motors are currently available from NEMA 8 to NEMA 34 with holding torque from 0.4Nm to 12.0 Nm. All these hybrid servo motors are integrated with 2-channel and 1,000-line optical incremental encoders. Moreover, custom winding, motor length, shaft, encoder resolution and other mechanical modifications are also available.
