Magnets in car oil pump motors are fundamental to creating the necessary magnetic fields that drive the motor. The interaction between the magnetic fields generated by the stator and rotor produces the mechanical rotation needed to operate the oil pump, ensuring proper lubrication and functioning of the car’s engine.

Process:

• Electric Current: When the car’s engine control unit (ECU) signals the need for oil circulation, it sends electric current to the motor.
• Magnetic Interaction: The current passing through the motor windings generates a magnetic field, which interacts with the stator’s magnetic field (from permanent magnets or electromagnets).
• Rotor Movement: This interaction creates a torque that turns the rotor.
• Pump Operation: The rotating rotor is connected to the pump mechanism (such as gears or vanes), causing it to draw oil from the sump and circulate it through the engine.

Advantages:

• Efficiency: Permanent magnet motors are generally more efficient as they do not require additional power to generate the stator’s magnetic field.
• Reliability: Fewer moving parts and less wear and tear in brushless designs lead to higher reliability.
• Compactness: Permanent magnet motors can be more compact, which is beneficial for automotive applications where space is limited.
