Characteristics of induction motor

Electric Motor is characterized by simple structure, easy to manufacture, inexpensive, reliable, durable, high efficiency and work with appropriate characteristics. The disadvantage is the power factor is poor. Asynchronous motor is running, it must absorb backward from the grid in the reactive power, its power factor is always less than 1. As the grid power factor can be compensated by other means, this does not prevent extensive use of asynchronous motor. For those single larger capacity, speed and constant production machinery commonly used synchronous motor drag as well.

Baking heat can be applied thermal infrared lamps or infrared control. Special Note: The baking temperature is not overheating, should be controlled at 125 ℃ or less. Current drying: the impedance of the motor according to farm size and power of the motor phase windings in series or parallel (single-phase motors can be of agricultural primary and secondary windings of the Electric Motor properly connected), then access a variable resistor to adjust the current to rated current value of about 60% power to dry.When personal electric shock when an accident or personal injury;Bearing temperature exceeds the allowed maximum temperature value;Motor temperature exceeds allowable value, and slowing down;

Because synchronous motor power factor is adjustable (can cosφ = 1 or lead). But not to say you can not drag this type of asynchronous motor manufacturing machinery, but were analyzed and compared according to the specific circumstances, to decide which Induction Motor. Asynchronous motor is running, the stator windings receive AC power, the rotor winding short-circuit itself. Because the relationship between electromagnetic induction, electromotive force generated in the rotor winding current, resulting in the electromagnetic torque. Therefore, the induction motor is also called induction motor.
