Product Description

BM Series Hollow Shaft BLDC Torque Motor

The BM Series Hollow Shaft Brushless DC Motor is a compact flat outrunner torque motor designed for robotic joints, gimbal systems, AGVs, automation equipment, and precision motion control applications. Featuring a hollow shaft structure, low-speed high-torque output, and thin pancake-style design, this motor series is ideal for integrated robotic mechanisms requiring lightweight construction and high rotational efficiency.

Designed with a three-phase outer rotor architecture, the BM Series supports sinusoidal and square wave drive control with external motor drivers. Multiple sizes and torque options are available to meet different robotic and industrial motion requirements.
