Welcome to Oriental Motor's "Engineering Notes" Blog:

Brushless motors have characteristics that make them excellent motors for speed control.  In this section, we will explain the technologies that enhance the performance of these motors.

Brushless motors have different methods of controlling current flow depending on the drive system.  In addition, to control the rotation speed and generated torque, it is necessary to control the amount of the motor current.  Here, we will explain the PWM method for controlling the motor current.

The BLV Series is one of two DC-input brushless motor speed control systems we offer.  While a brushless motor with hall-effect sensor feedback provides constant torque, wide speed range, and speed regulation, the BLV driver offers unique functions designed for mobile robots, such as low battery operation and ramp operation.
