    Motor Picture


    Motor Application


    The Advantages of BLDC Motor


    1. The traditional brushed mechanical commutation method is removed and electronic commutation is adopted, with a fully enclosed structure, which makes the performance more reliable and the failure rate lower.


    2. It has better external characteristics, can output greater torque at low speed, and can provide relatively large starting torque.


    3. The no-load current is small, the speed range is relatively wide, and it can operate at full power at different speeds.


    The Working Principle of BLDC Motor


    The BLDC Motor adopts electronic commutation, the coil does not move and the magnetic pole rotates. The brushless DC motor uses a set of electronic equipment to sense the position of the permanent magnet poles through the Hall switch SS2712. Based on this perception, the electronic circuit is used to timely switch the direction of the current in the coil to ensure that the magnetic force in the correct direction is generated motor.


    The Structure of BLDC Motor


    The BLDC Motor mainly consists of a rotor made of permanent magnet material, a stator with coil windings and a position sensor (optional). It can be seen that it has many things in common with DC motors. The structures of the stator and rotor are similar (the original stator becomes a rotor, and the rotor becomes a stator), and the winding connections are basically the same. However, there is an obvious difference in their structure: the brushless DC motor does not have the commutator and brushes in the DC motor, but is replaced by a position sensor.


    Types of BLDC Motor


    • 1.1 Inner rotor type

    For the inner rotor type, the rotating part is located inside the stator and the segmented permanent magnets are mounted on the outer surface of the rotor. Due to the small rotor diameter and small moment of inertia, it has good acceleration and deceleration response. In addition, since the stator is close to the motor surface and has good heat dissipation, a compact motor with high output power can be realized.


    This is a typical BLDC Motor configuration and is used in a wide range of applications. In my opinion, they could save a lot of space or be an effective choice for material handling applications, such as driving pulleys on conveyor belts and/or moving the wheels of an AGV.


    • 1.2 External rotor type

    For the external rotor type, the rotor is located outside the stator and the permanent magnets are located inside the rotor. Segmented permanent magnets are mounted on the inner surface of the rotor. The position of the stator and permanent magnets is opposite to that of the inner rotor type. The cup-shaped rotor has a large inertia moment and poor acceleration and deceleration response, making it unsuitable for flexible movement, but it can still provide good speed stability.


    Due to the larger rotor diameter, more magnets can be installed compared to the inner rotor type, and the number of poles is increased compared to the inner rotor type. This makes it possible to achieve high output power in a compact size. However, since the winding is located inside and has poor heat dissipation, the winding easily generates heat, which limits the working time. In drone motors with external rotor brushless motors, the rotor cup has ventilation holes, and the wind generated by the spiral helps keep the windings cool.


    The application range of the external rotor type is narrow. The rotor's large inertia makes quick starts and stops more difficult. Poor cooling limits working time. However, if the motor is designed with thermal ventilation, radiation or cooling in mind, applications can extend to cooling fans and drones, among others.


    • 1.3 Disc rotor type

    For disc rotor types, the stator is formed by mounting windings and pole sensors on a circuit board. This type of motor is very thin because the plate permanent magnets are located on the surface of the rotor, facing the stator. It is used to maintain a stable and fixed speed under light loads. There is no shaft, so the load is mounted on the rotor.


    This type of motor is commonly used in hard drives and disk drives for CVD, Blu-ray Disc, and other media, but it can be expanded to other applications where space is limited.
