Motor matching includes following aspects:
motor parameter selection motor and related accessory matching motor and controller matching
Motor is the driving component of an EV. IAT has rich experience in motor selection for EV. Based on the self-developed EV Motor and Battery Matching System and in compliance with the customers’requirements on vehicle power performance (Instantaneous Top Speed, Continued Top Speed, Max. Grade Angle, and 0-100 km/h Acceleration Time), we will preliminarily select the basic parameters for motor(Max. output, rated power, Max. torque, Max. rotation speed, rated rotation speed etc…). According to the basic parameters and different matching types of motors in our database, we pick up the right one suited to the requirements of customers. Then we will calibrate the performance of EV as per those actual motor parameters. By multiple such combinations and analysis, the high cost-effective motor that is compliant with the customer requirement can be selected.
The parameters such as cooling tube layout and cooling grille area can be matched according to the features and related accessory of the motor after the confirmation on motor parameters.
Motor controller is the most important part to precisely control the motor movement. At present, the motor and the motor controller are packed together for sale in domestic market, but the interface definitions between the motor controller & vehicle controller and battery management system are decided by the OEM. IAT has rich experience in the field of electronic control to confirm the interface definitions between the motor controller & vehicle controller and battery management system and ensure the stable running of system while at the same time reduce the load of bus.
