With the advancement of the electric vehicle technology, selecting the correct motor is becoming of utmost importance on various vehicle platforms. In A80 electric drive, the motor works with the battery, control unit, transmission, and vehicle control unit in order to get its acceleration, efficiency, performance of driving, and reliability.
That is why the selection of the motor needs to be based on vehicle's operational requirements instead of just on the power rate.
Power and Torque Requirements
Power and torque must be considered when selecting an A80 Electric Motor. In the course of starting, acceleration, climbing, or during the time of operation under heavy load conditions, the motor must have enough torque in order to deal with the vehicle resistance.
Moreover, the motor's speed, transmission ratio, size of the wheels, and power determine the highest speed of the vehicle, which should be taken into consideration when selecting the motor.
Vehicle weight, target speed, climbing gradient, and transmission configuration must be taken into account when choosing the motor.
Efficiency and Battery Utilization
The efficiency of the motor influences the efficiency of the battery, which means that losses of electricity in the motor not only take battery power from it but generate heat simultaneously.
However, the motor's efficiency is changed depending on the load and speed. Electric vehicles operate in various conditions: when they are accelerating, when moving slowly, when cruising, and when climbing.
Therefore, it is necessary that engineers check the motor's efficiency of the motor at all the operational conditions of the vehicle.
Motor and Controller Matching
Motor and controller are to be treated as a single electric drive system. The controller is to manage the motor torque, speed, and current according to the vehicle’s operational needs.
When the motor and controller are not properly matched, difficulties arise involving starting torque being unsatisfactory, overload of currents, speed control being unstable, and the temperature rising abnormally.
Depending on the motor and control strategy, the encoders should be selected or not. Battery voltage, controller current capacity, motor speed range, and the information about the feedback should be confirmed prior to developing the system.
Thermal and Mechanical Requirements
During periods of excessive or prolonged power, the temperature of the electric motor may rise. High temperature can have adverse effects on the workings of parts such as the insulation and bearings.
It is vital, therefore, to think about the methods of heat removal, the orientation of the drive, the temperature of the atmosphere, the loads provided, and the actual working time of the motor.
The mechanical compatibility of the motor is very important as well. The dimensions of the motor mounting, the size of the shaft, the shape of the flange, the kind of the coupling, the direction of rotation, and the space for installation should be identified.
If the previous motor is to be replaced, it is suggested to compare the installation drawing of the new motor with the one of the existing electric motor for the safety of installation.
Technology of PMS Pavement Electric Drive Motors
PMS electric motor technology is characterized by high efficiency, high power density, and controllability, which allows using the motor in vehicles.
Nevertheless, the choice of the electric motor cannot be made without considering all parameters of the vehicle. The voltage of the batteries, torque produced by the vehicle, its maximum speed, refrigerating conditions for the motors, the design of the controller, as well as the cost of the whole project.
