BMU Series Brushless DC Motor Speed Control Systems (Old Connector)

The 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 Combination-type Parallel Shaft and Right-Angle Hollow Shaft Geared models are available in standard, IP65 and IP66 rated versions.

Single-Phase 100-120 VAC or Single-Phase/Three-Phase 200-240 VAC

*Some gear types are limited to 3,600 r/min max. input speed, (1:45 speed ratio).
