Variable Speed Gear Motors
Variable-speed gear motors combine a gear reducer with a motor whose speed and torque are controlled by a VFD, DC drive, or mechanical variator.

Overview
Variable-speed gear motors combine a gear reducer with a motor whose speed and torque are controlled by a VFD, DC drive, or mechanical variator. The combination matches the driven equipment’s actual demand instead of the motor’s nameplate speed. Northwest Power Products supplies variable-speed gear motors and drive packages from Nord, SEW-Eurodrive, Sumitomo, and other major OEMs, with cross-referencing for older or discontinued units on frame, ratio, torque, voltage, and drive compatibility. They pair motors with matched drives when that is the cleaner path, repair existing units when the housing and electrical are recoverable, and confirm cooling and insulation specs are correct for the operating speed range before shipping.
