power hall brushless drive with a wide supply range of 1236V, a maximum current of 15A, and a maximum power of 500W. Most motors have been tested for good compatibility, while a small number of motors may not be fully compatible. It is to test yourself. Supports positive and reverse switching, with speed regulation via a potentiometer. The potentiometer is typically 1050K, and speed regulation can also be achieved with a PWM 5V signal. It is strictly prohibited to connect the positive and negative poles of input power incorrectly. The UVW threephase output must not be short circuited or burned. The unit is equipped with an 18 mm thick heat sink. The ability to sustain power depends on actual heating; if heating is large, a fan should be added for forced air cooling. For safety and reliability, use an adjustable power supply with current limiting to test whether the actual noload current is abnormal, in to prevent power from burning during abnormal moments. Use scenarios and applications: Custom electric drive for bicycles or small electric vehicles requiring 1236V, up to 500W, and 15A peak current. Robotics and automation projects that need forward and reverse motor control with adjustable speed via potentiometer or PWM signal. Educational benches and prototype testing where safe, controlled BLDC drive operation and learning of speed regulation and protection features are valuable.
