The article uses the example of a fully automatic washing machine motor. This is a single-phase induction motor suitable for fully automatic pulsator washing machines. The parameters marked on the nameplate of such a fully automatic washing machine motor mainly include product model, motor type, rated voltage, frequency, output power, rated current, capacitance, number of stages, insulation level, protection level, circuit diagram, manufacturer, and production time.

Here are the details of the parameters:

  1. XD-150: XD represents a fully automatic washing machine motor or a washing machine washing capacitor running asynchronous motor, and 150 represents 150W. The model of the washing machine motor is usually distinguished by the type of motor and output power. If marked YYG, it means it is a washing machine dehydration motor.

  2. WASH MOTOR: This refers to the washing machine washing motor. It generally indicates the type of motor and its use. In some cases, it also notes the aluminum wire winding to distinguish it from the copper wire winding. If marked SPIN MOTOR, it means it is a washing machine dehydration motor.

  3. 220V: This is the rated voltage. The applicable range of the motor's rated voltage needs special attention for export orders of household washing machine motors. China uses 220V, while European countries like the UK, Germany, and France, as well as Asian countries like India, Indonesia, and Malaysia use 230V. Japan uses 100V.

  4. 50Hz: This is the AC frequency, i.e., the frequency of the AC power source connected to the motor, which switches polarity at pulses of 50Hz or 60Hz. China, the UK, Germany, France, India, Indonesia, and Japan all use 50Hz, while the US uses 60Hz.

  5. 150W: This is the output power of the motor. The output power of fully automatic washing machine motors produced by Dili Motors usually ranges from 70W to 240W. The output power of semi-automatic washing machine washing motors ranges from 60W to 220W, and that of semi-automatic washing machine dehydration motors ranges from 30W to 90W.

  6. 1.5A: This is the rated current of the motor. The rated current refers to the current when running at the rated power under the rated voltage. The rated current of fully automatic washing machine motors produced by Dili Motors usually ranges from 0.75A±15% to 1.9W±15%. The rated current of semi-automatic washing machine washing motors ranges from 0.75A±15% to 1.9W±15%, and that of semi-automatic washing machine dehydration motors ranges from 0.55A±15% to 0.95W±15%.

  7. 4P: This is the number of stages of the motor, determined by the number of pole pairs. Each coil group of the motor will produce a pair of N, S poles. One pair of poles is 2P, and two pairs of poles are 4P. Both fully automatic washing machine motors and semi-automatic washing machine motors are usually 4P.

  8. 10μF/450V: The nameplate lists the size of the maximum power factor correction capacitor. 10μF is the capacitance, and 450V is the withstand voltage, i.e., the maximum voltage that the capacitor can load. Exceeding the withstand voltage may damage the motor or other components. Induction motors rotatethe magnetic field by using capacitors to create sinusoidal waves of power supply and phase shift.

  9. CLASS F: This refers to the insulation class, usually a letter name, including "A", "B" or "F", etc., depending on the ability of the insulation material used in the motor winding to withstand a given working temperature, that is, the ambient temperature plus the temperature rise. Class B insulation materials generally withstand a working temperature of 130℃, and Class F can withstand 155℃.

  10. MADE IN CHINA: Since this is an export order for HOIIY MOTOR Dili Motors, it shows that it is made in China. Generally, domestic sales will not mark this on the nameplate.

  11. 2022.08: This is the production time of the motor. Generally speaking, except for rush orders, washing machine motor export orders have a production and delivery cycle process, so it is recommended that overseas buyers arrange orders in advance. The earlier the order is placed, the earlier the production and delivery, so as not to be overdue.

  12. The wiring on the far right: The circuit diagram above has YELLOW, GRAY, and BLUE, that is, yellow, gray, and blue. The color of the wires is not limited to the above three colors. Which wire the color of the wire represents, whether it is a live wire, a neutral wire, or a ground wire, is not clearly stipulated. Each washing machine manufacturer has a standard and can only be connected according to the circuit diagram.
