The washing machines on the market are mainly divided into three types: double-cylinder washing machines, pulsator washing machines and drum washing machines. The washing machines mainly have two working modes: washing and dehydration.

The two-cylinder washing machine assembly motor is induction motor, including washing motor and dehydration motor; the pulsator washing machine assembly motor is induction motor and DD motor, including washing motor; the drum washing machine assembly motor is series motor, DD motor, BPM motor, DD motor And BPM motors are all DC brushless motors. Brushless motors have the advantages of low noise, high efficiency, and low vibration during operation, and their market share continues to increase.

The washing machine induction motor is a single-phase AC asynchronous single-speed motor, which consists of a stator and a cast aluminum rotor. It has three lead wires: main phase, secondary phase, and common terminal.Capacitive start mode is adopted.

Washing machine series excitation motor (full name is single-phase series excitation speed regulating motor), which belongs to AC brush motor, has two input power lines, is composed of stator and armature rotor, and has 32 armature commutator segments.

Washing machine DD motor: DD is the English acronym for direct drive, which can be translated as a DC brushless direct drive motor. The motor consists of a stator and a permanent magnet outer rotor (because the magnetic tile is stuck on the rotor, it is called a permanent magnet outer rotor) , The rotor is connected with the washing drum, the motor is equipped with a Hall plate, and the washing machine is mainly composed of a controller, a driver and a motor.

Washing machine BPM motor: BPM is the English acronym for Brushless Permanent Magnet Motor. The motor consists of a stator and a permanent magnet inner rotor (the magnetic sheet is embedded in the rotor, so it is called a permanent magnet inner rotor). The motor is connected with the washing tub through a pulley, and the washing machine mainly includes a controller, a driver and a motor.

The washing machine motor test mainly includes three categories: induction motor test, series motor test, and brushless motor test. Each category is divided into stator test, (cast aluminum/permanent magnet) rotor test, and complete machine (loading) test. The structure and working principle are completely different, so the test difference is also large. AIP focuses on global motor testing. In 2013, it exported the BPM brushless motor loading test system to Thailand. After years of technical investment, it has formed a complete set of washing machine motor testing solutions.

AIP provides a one-stop motor test solution, no matter what type of washing machine motor you are, AIP can provide you with stator/rotor test to complete machine test, from workshop test to laboratory test, from offline test to online test A complete set of testing solutions, testing motors, it is enough to choose AIP.
