Description
Technical field
The utility model relates to magnetic actuator field, relates in particular to a kind of magnetic actuator of adjustable speed.
Background technology
General magnetic actuator is mainly by having the driving disc spacing pressing of strong magnets and being that driven disc two parts that material is made form with copper or aluminium.Driving disc spacing pressing is fixed on motor drive shaft, and driven disc is fixed on bearing axle, between driven disc and driving disc spacing pressing, has air gap.Connect by magnetic, the connection of motor and load is connected to (machinery connects firmly) by original contact and changes contactless connection (magnetic is flexible coupling) into, the output torque reaching on bearing axle by the air gap regulating between driving disc spacing pressing and driven disc changes, and then obtains required loading speed.
The service performance that significantly improvement system of magnetic actuator starts, at the beginning of starting load, motor is via magnetic actuator No Load Start, not only can reduce the starting current of motor, reduce thermal shock load and the impact on electric power system on motor, and then saves energy the working life that extends motor, and effectively reduce startup moment, to the damaging impact tension force of drive system belt conveyor, eliminate the concussion producing when conveyer starts, can also significantly alleviate the suffered startup of drive system itself impacts, extend the useful life of the vital parts such as belt and idle pulley, the security reliability of lifting means operation, and effectively reduce maintenance of equipment and fault time cost.Compared to traditional driver, magnetic actuator provides more progressive structure really, has using value.
