Brushless DC Motors FAQ

Read below for some commonly asked questions and answers relating to BLDC motors.

The main difference between brushless DC motors and brushed DC motors is the way they are powered. Brushed DC motors rely on mechanical brushes and a mechanical commutator to transfer power to the motor, while brushless DC motors are powered by an electronic controller that switches the polarity of the current in the coils to keep the motor rotating. This allows brushless DC motors to operate with greater efficiency and quieter operation than their brushed counterparts. Brushless DC motors also require less maintenance than brushed or synchronous motor systems, as there are no mechanical components to wear out.
A brushless DC motor (also known as a BLDC motor) is an electronically commutated motor that runs on direct current. It does not have mechanical brushes and instead relies on a permanent magnet or electromagnet to induce torque. Rotational speed is controlled using electronic control circuitry, connected to a power source and the motor’s winding. This type of motor is known for having a wide speed range and can reach speeds up to 100,000 rpm. Brushless DC motors have several advantages over traditional motors, such as increased efficiency, higher power-to-weight ratio, and faster speeds. They are often used in applications where high efficiency and long-life cycles are necessary, such as robotics, computer peripherals, power tools, and automotive applications. BLDC motors also tend to deliver quieter, more reliable, and less maintenance-intensive performance than other types of DC, permanent magnet motors, and induction motor systems.
A brushless DC motor uses an internal permanent magnet to spin a rotor around the stator poles. This spinning action, caused by the interaction of the permanent magnet and the magnetic fields generated within the stator, creates torque. The motor’s power and speed are regulated by the strength of the permanent magnet and the current sent through the stator windings. A motor controller is used to manage the current sent through the stator windings, allowing for precise speed and torque control, comparable to servo motors. Brushless DC motors can vary in size and power, allowing them to be used in a variety of applications.
The BLDC motor series can be broadly divided into two main categories: sensor-based and sensorless motors.
  • Sensor-based brushless motors utilize hall sensors to detect the rotor position and enable the motor to start up without slipping or overshooting.
  • Sensorless brushless motors are simpler and less expensive but may not be as precise when starting up and reaching desired initial torque.

Brushed DC motors and brushless DC motors both use direct current to turn electrical energy into mechanical energy, but they differ in how they produce this energy. Brushed DC motors use brushes to create electrical contact between the rotor and stationary wires, allowing current to flow through the rotor and generate torque.

Brushless DC units use powerful rare earth magnets instead of brushes to create a rotating magnetic field. This makes them quieter and more efficient than brushed DC motors – but they are also more expensive and require an electronic driver module to function.
