The BMU SeThe BMU Series features a compact, high-power and high-efficiency brushless DC motor and is combined with an easy to use, easy to set speed controller. The entire motor structure features our latest brushless DC motor technology and has been innovated in pursuit of the optimal performance. The BMU Series has a maximum speed of 4000 r/min. Speed ratio of 1:50 (80 to 4000 r/min) is achieved. Round Shaft and Geared models available.

  • 200 W (1/4 HP)
  • Single-Phase 100-120 VAC or Single-Phase/Three-Phase 200-240 VAC
  • Permissible Torque
    • Round Shaft = 90 oz-in (0.637 N·m)
    • Parallel Shaft Gear = 21. ~ 4584 lb-in (2.4 ~ 518 N·m)
    • Right-Angle Hollow Shaft Gear = 18.59 ~ 732 lb-in (2.1 ~ 82.8 N·m)
    • Hollow Shaft Flat Gear = 47 ~ 470 lb-in (5.4 ~ 54 N·m)


Some gear types are limited to 3,600 r/min max. input speed, (1:45 speed ratio). ries features a compact, high-power and high-efficiency brushless DC motor and is combined with an easy to use, easy to set speed controller.
