What does the motor number of an electric vehicle mean?
2 Answers
Electric vehicle motor numbers contain the motor's operating voltage, power rating, production date, and serial number. Here are the specific details about motor numbers: 1. Example: A motor serial number like 60v2000w170628609272 indicates that 60v is the operating voltage, 2000w is the power rating, 170628 is the production date, and the remaining digits are the motor's serial number. 2. Overview: An electric motor is an electromagnetic device that converts or transfers electrical energy based on the principle of electromagnetic induction. Also known as a motor, it is represented by the letter "M" in circuit diagrams (older standards used "D"). Its primary function is to generate driving torque, serving as the power source for electric vehicles.
When I first bought my car, I also wondered about the meaning of this motor number. Later, I found out it's like the ID number of the motor. Every installed motor has a unique stamped code when it leaves the factory, usually engraved on the side of the motor housing, consisting of a combination of letters and numbers in a dozen or so characters. This code includes information about the manufacturer, motor model specifications, and production batch serial number. When registering the license plate, the vehicle management office needs to imprint this number for archiving, just as important as the engine number of traditional cars. If the vehicle is involved in a collision and the motor needs to be replaced, the repair shop must use this number to match the original spare parts. Once, when my car had abnormal vibrations while running, the 4S shop mechanic first checked the motor number to retrieve the parameter documents and diagnosed it as a magnetic pole displacement issue.
