DESC:MOTOR CONTROLLER FOR ELECTRIC VEHICLE
CROSS REFERENCE TO RELATED APPLICATIONS
The present application claims priority from Indian Provisional Patent Application No. 202321075056 filed on 03/11/2023, the entirety of which is incorporated herein by a reference.
TECHNICAL FIELD
Generally, the present disclosure relates to the field of motor controller. Particularly, the present disclosure relates to a system and method for controlling a motor of an electric vehicle(s).
BACKGROUND
A motor controller is an electronic device or system that manages operation(s) of a motor. The motor controller controls the motor parameters such as (but not limited to) speed, direction, and torque based on input signals received from a microprocessor or control system. The importance of motors and motor controllers in electric vehicles (EVs) has surged in recent times due to the rapid evolution of the automotive industry and the global push for sustainability.
Conventionally, the motor controllers employ a variable resistor, or a rheostat to adjust the voltage supplied to the motor. The rheostat is connected in series with the motor and power supply. Consequently, the current flowing through the motor is same as the current flowing through the rheostat. Further, the increase in the rheostat resistance reduces the voltage across the motor. Subsequently, the decrease in voltage results in a reduction of the motor speed as the power delivered to the motor is reduced. Conversely, if the resistance is decreased, more voltage is supplied to the motor, thereby, increasing the motor speed. Therefore, the variable resistor controls the motor voltage by adjusting the resistance in the circuit, thereby changing the motor speed.
However, there are certain underlining problems associated with the above-mentioned existing mechanism of controlling the motor of the electric vehicle. For instance, at lower resistance, small range adjustments in the resistance lead to a large change in motor speed. Consequently, the precise speed control of the motor is difficult at lower resistance. Further, the rheostat dissipates power as heat, leading to significant energy loss. Furthermore, due to the varying operating parameters of the vehicle, the relationship between the resistance of the motor and motor speed is non-linear. Therefore, achieving a predictable response from the motor is challenging, and hence, unstable performance of the motor is observed.
Therefore, there exists a need for a mechanism of controlling the motor of the electric vehicle that is accurate, safe, and overcomes one or more problems as mentioned above.
