The QPCSDBBBB20 (Quasi-Phase Controlled Single-Direction Bidirectional Bipolar Brushless DC Motor) is a motor specifically designed for high speed, high torque applications in industrial and automation environments. It is a brushless DC motor and is usually driven by three-phase alternating current (AC) or three-phase direct current (DC) power supply. It is especially suitable for applications such as industrial robots, servo systems, pumps, fans and other loads which require high moment of inertia and a high starting torque. The working principle of the QPCSDBBBB20 motor is based on the combination of two laws: the law of conservation of energy and the principle of magnetic field control.

The motor consists of a stator (stationary part) and a rotor (rotating part). The stator has three sets of windings (A, B and C) which are connected in a three-phase configuration. The rotor comprises of commutator segments and permanent magnets. The stator windings produce a rotating magnetic field in the air gap between the stator and the rotor. As the rotor rotates with the rotating magnetic field, the magnetic flux from the stator and rotor interact, producing force that drives the rotor, thus converting electrical energy into mechanical energy. The direction of the rotational force of the rotor is determined by the direction of the rotating magnetic field.

In the QPCSDBBBB20 motor, the direction of the magnetic field in the air gap between the stator and the rotor is controlled by the commutation of the stator windings. By controlling the switching sequence of the stator windings, the commutation of the stator windings is done in a quasi-phase change mode, which enables the motor to achieve high switching frequency and torque control. The key components of this motor are the three-phase power supply, the motor control circuit, the permanent magnets and the commutator.

The QPCSDBBBB20 motor offers several advantages compared to traditional brushless DC motors, such as low power consumption, higher torque and higher speed. The main application fields of this motor include factories, robot automation, pumps, fans and other heavy loads that require high starting torque and large moment of inertia. In addition, this motor is highly reliable and durable, making it suitable for use in harsh environments.

In conclusion, the QPCSDBBBB20 motor is a type of brushless DC motor specifically designed for industrial automation and other high speed, high torque applications. It doesn’t require brushes or a commutator, which makes it easier to maintain and highly reliable. The working principle of the motor is based on the conservation of energy and the principle of magnetic field control, which is achieved through the commutation of the stator windings. This makes the motor suitable for a wide range of applications, including factories, robotics, pumps, fans and other heavy loads.
