What's on the nameplate of three-phase asynchronous motor?
The nameplate of three-phase asynchronous motor usually includes the following contents:

Motor model: This usually includes the series, pole number, rated power, rated voltage, rated current and other information of the motor.

Manufacturer: This is the manufacturer information of the motor, including the name and trademark of the manufacturer.

Ex-factory date: the date when the motor is produced, so as to facilitate users to know the service life of the motor.

Motor connection: star or triangle, which will be written on the nameplate. This information is very important because it determines the connection mode of the motor.

Working system: indicates the working state of the motor, such as continuous working, short-time working and intermittent working.

Insulation grade: the insulation grade of the motor determines the heat resistance of the motor and indirectly determines the life of the motor. General insulation levels are A, E, B, F, H and C.

Protection grade: the protection grade of the motor determines the dustproof and waterproof ability of the motor. The higher the grade, the stronger the dustproof and waterproof ability.

Grounding type: the motor must have a good grounding device to ensure safety, and the grounding type will be indicated on the nameplate.

Working temperature: the ambient temperature when the motor works normally. If this temperature is exceeded, the motor will overheat.

Maximum allowable voltage: the maximum allowable voltage of the motor within a specified time. If this voltage is exceeded, the motor may be burnt out.

Maximum allowable current: the maximum allowable current of the motor within a specified time. If this current is exceeded, the motor may be burnt out.

Rated speed: revolutions per minute corresponding to the rated power of the motor.

Power factor: reflects the electric energy utilization rate of the motor.

Noise level: It reflects the noise level of the motor.
