Steel used in motor stator laminations is typically silicon steel, also known as electrical steel. This type of steel is specially designed to reduce energy losses due to hysteresis and eddy currents. Common grades like M19, M27, and M36 are chosen based on their silicon content and magnetic properties to enhance motor efficiency and performance.
Motor core laminations generally range in thickness from 0.2mm to 0.5mm. Thinner laminations improve electromagnetic performance but have lower mechanical strength. Thicker laminations offer higher mechanical strength but reduced electromagnetic efficiency. The choice of thickness depends on specific application requirements, balancing performance and durability to meet the motor’s needs effectively.
