    How does a BLDC Motor Control Speed with Controller?

    Brushless DC motor kit consists of a motor and a driver, and is a typical mechatronic product. Because the brushless DC motor operates in a self-controlled manner, it will not add a starting winding to the rotor like a synchronous motor with heavy-load starting under variable frequency speed regulation, nor will it cause oscillation and loss of step when the load changes suddenly. Today we're going to study how to connect a brushless motor to a driver and control speed.

    This is the BLDC motor controller.

    This is the 50W 24V BLDC motor equipped with 8 wires. Red wire is Hall voltage input line (VCC), black one is Hall voltage ground (GND). Yellow, white and blue wires are hall U, hall V and hall W wire. Orange, green and brown wires are U, V, W phase of the driver.

    Now, theĀ BLDC motor starts to connect with the driver.

    After all the wiring is completed, the electrical commissioning shall be started.
    The indicator is green for normal and red for fault.
    Note: At this point the BRK port is connected to GND.

    Indicator is green for normal

    We can adjust the speed through the driver with its own speed regulator.

    CW is acceleration, CCW is deceleration
