Combining with planetary geartrains, Dynetic Systems’ family of NEMA 23 and 34 integrated brushless PM servo gear motors provide gear motor torque values from 26.5 lb/in. to 198 lb/in. and from 224 lb/in. to 633 lb/in., respectively. Single-, dual-, and three-stage geartrains exhibit 10 gear ratios ranging from 16:1 to 1,012:1. The motors offer IP 65 or IP 67 configurations, a bearing bore design for damping noise, and Neodymium magnets. The devices interface to sinusoidal drives from 12 VDC to 320 VDC in aerospace actuator, industrial machine, and medical equipment applications. Feedback devices are available for inclusion in the motor package, including hall devices, resolvers, and encoders.
