Vibration Motors

There are two basic types of vibration motor. An eccentric rotating mass vibration motor (ERM) uses a small unbalanced mass on a DC motor when it rotates it creates a force that translates to vibrations. A linear resonant actuator (LRA) contains a small internal mass attached to a spring, which creates a force when driven. As specialists in the supply and design of vibration motors, you can

What is meant by electrical braking of a motor?

When a motor is in moving state, it has some kinetic energy stored in it. If you have to stop the motor, then you have to remove or dissipate this energy(commonly

Self-starting and soft-start controllers. A soft-start controller is used in three-phase AC induction motors to reduce the load on the self-starting motor and the current surge of the motor during start-up. This reduces the mechanical stress on the motor and shaft, as well as the electrodynamic stresses on the attached power cables and electrical distribution network, extending the lifespan of
