Problems solved by technology

Since the volume of the motor is proportional to the electromagnetic torque, for the same motor, its power is proportional to the product of the motor speed and torque. Due to the effect of torque, the number of poles of the motor is often designed very large, and the structure of the generator becomes very complicated and bulky, requiring hoisting and maintenance of the whole machine. Therefore, this method has the disadvantages of large size, heavy weight, high manufacturing cost, and installation Inconvenient transportation and other issues
