Brushless motors can be designed with single or double windings, which refer to the number of electrical windings present in the motor. The winding configuration significantly affects the motor’s performance, efficiency, and application suitability.

  1. Single Winding Brushless Motor:
    • Single-winding brushless motors have one set of windings in their stator. This means that each stator tooth typically has only one coil wound around it.
    • They are simpler in construction, more cost-effective, and easier to manufacture.
    • These motors are generally used in applications where a single-speed operation is acceptable. They may be more suitable for applications where speed control isn’t critical or where the motor is dedicated to performing a specific task at a constant speed.
    • Single-winding motors are often found in applications such as fans, pumps, and certain fixed-speed industrial machinery.
  2. Double Winding Brushless Motor:
    • Double-winding brushless motors feature two sets of windings in the stator.
    • They offer greater flexibility in speed control and torque output. By independently controlling the two windings, these motors can achieve a broader range of speeds and torque characteristics, making them suitable for variable speed applications.
    • Double-winding motors are more complex and may be costlier to produce due to the additional winding and control circuitry required.
    • They are commonly used in applications where variable speed, precise control, and dynamic performance are necessary. These motors are often found in robotics, industrial automation, electric vehicles, and other applications requiring variable speed and precise control.

The choice between single and double winding brushless motors depends on the specific application requirements. Single winding motors are simpler and cost-effective but offer fixed-speed operation, whereas double winding motors provide more flexibility in speed control and torque characteristics, albeit at a higher cost and complexity.
