Aiming at some problems existing in the current mechanical soft starter

a new magnetorheological soft starter is proposed and designed.The theoretical torque model of disk-shaped magnetorheological actuator is built

a mechanical combined structure of magnetorheological soft starter is designed;the principle

the heat dissipation structure and the magnetic circuit structure design are specified.The magnetorheological soft starter can not only meet the function requirements

but also reduce the requirement of driving motor and decrease the volume significantly;the reversible conversion of magnetorheological fluid from solid state to liquid state completes within some milliseconds

making the soft starter respond faster and improving the transmission efficiency.
