Basic knowledge of electric motors
1. Introduction to Electric Motors An electric motor is a device that converts electrical energy into mechanical energy. It utilizes an energized coil (i.e. stator winding) to generate a rotating magnetic field and act on the rotor (such as a squirrel cage closed aluminum frame) to form a magneto...Read more -
Advantages, Difficulties, and New Developments of Axial Flux Motors
Compared to radial flux motors, axial flux motors have many advantages in electric vehicle design. For example, axial flux motors can change the design of the powertrain by moving the motor from the axle to the inside of the wheels. 1.Axis of power Axial flux motors are receiving increasing atte...Read more -
Hollow technology of motor shaft
The motor shaft is hollow, with good heat dissipation performance and can promote lightweight of the motor. Previously, motor shafts were mostly solid, but due to the use of motor shafts, the stress was often concentrated on the surface of the shaft, and the stress on the core was relatively sm...Read more -
What are the methods to reduce the starting current of the motor?
1. Direct starting Direct starting is the process of directly connecting the stator winding of an electric motor to the power supply and starting at rated voltage. It has the characteristics of high starting torque and short starting time, and is also the simplest, most economical, and most rel...Read more -
The five most common and practical cooling methods for electric motors
