PURPOSE:To simplify the constitution and improve safety during shutting off the power, etc., by forming a manual torque amplification device better suited for an electric power handle, etc., so that it drives load by a reluctance type motor. CONSTITUTION:The upper end of an elastic bar spring (torsion spring) 18 is fixed to the lower end of a rotary shaft 4a of a manual handle 4 of a mini car, and the upper end of a rotary shaft 5 of a reluctance type motor S is fitted on the lower end of the spring 18. A substrate of the motor S is fixed to a body, and the rotary shaft 5 is interlocked with and connected to a steering means of a wheel C or a load through a reduction gear (not shown). The motor S has a rotor 1 provided with salient-poles 1a, 1b,... and a fixed armature 16 provided with magnetic poles 16a, 16b,... opposed to the above salient -poles, and exciting coils 17a, 17b,... are wound respectively around each magnetic pole 16a, 16b,... when exciting currents are fed to the exciting coils 17a, 17b,... in response to load or driving torque, auxiliary steering force can be obtained. |
