30W Brushless Motor Driver
Product Description

6BH030A-K25 / 6BH030GB-K25

The BH series brushless motor is a thin, small, high-efficiency, low-noise brushless motor. The driver adopts a DC24V lightweight substrate design, which is easy to install on any equipment and machine. The wiring is simple, just connect the motor and driver. Just connect and it's ready to go.

The brushless design of the brushless motor reduces maintenance requirements and extends service life. It has functions such as speed setting, torque limit setting, acceleration or deceleration time setting, protection function, and alarm output.

These advantages make brushless motors widely used in various fields such as power tools, electric scooters, conveyor belt equipment, and packaging machinery. With the demand for environmentally sustainable and low energy consumption, the application scope of brushless motors has further expanded, becoming the core driving component of more equipment and systems.

Our products will help you increase productivity, reduce costs, and maintain your competitive advantage.
