Rohnert Park, CA—Parker’s Electromechanical Automation Division released two high-torque motors from its MaxPlusPlus (MPP) servomotor family. The company says the higher-performance MPP230 and MPP270 offer the torque users need for high-power applications, such as press feeders, tube benders, and plastic extruders.
The frame sizes increase the torque range up to 162 Nm of continuous stall torque and a peak torque of 513 Nm. Standard options, such as a resolver and Stegmann single- and multi-turn absolute encoders, along with a 24 V brake option and a shaft seal, are available. The motors are UL and CE certified. All MPP motors can be customized with a multitude of features, such as custom output shaft dimensions, various front end-cap mounts, or special windings.
Designed for the demanding applications found in today’s high-performance servo systems, Parker claims the motors offer lower inertia and higher power, all in a smaller package than conventional motors. They feature segmented lamination technology, which can yield up to 40% higher torque per unit size than conventionally wound servo motors. “Potted” stators improve heat transfer for better thermal efficiency, resulting in increased torque at the motor shaft. High-performance neodymium magnets are employed for higher acceleration rates.
