The difference between DC motor and AC motor in electric stacker
Advantages of DC motors1. DC motor has good starting characteristics and speed characteristics2., the torque of DC motor is relatively large3., maintenance is cheaper.4. DC motor DC relative to the exchange of energy-saving environmental protection.
Disadvantages of DC motor1. direct current motor manufacturing is more expensive2. carbon brush
Advantages of AC motor1. AC motors are cheaper to manufacture.The development of 2. vector frequency conversion technology can be simulated by frequency conversion motor into direct current3. with respect to the DC motor has enough advantages in simple structure, easy maintenance, low requirement to the environment and energy saving and improve productivity and so on, the AC speed control has been widely used in industrial and agricultural production, transportation, national defense and daily life.
