Japanese Patent JPH0139309
Kind Code:
B2
Abstract:
An electromotive control drive mechanism, in particular for industrial sewing machines, comprises a continuously drivable motor and a brake/clutch unit connected therewith. A clutch disk connected in a rotationally fixed manner with a driven shaft can, by axial movement and by overcoming a clutch air gap, be brought into frictional engagement with a clutch support which is connected in a rotationally fixed manner with the rotor of the motor. A brake disk connected in a rotationally fixed manner with the driven shaft can be brought into frictional engagement with a brake support which is rotationally fixed. A clutch coil and a brake coil are also provided. In order to reduce the expense of the brake/clutch unit without burdensome actuation noises arising, only one clutch/brake disk is provided, and mechanisms are provided for adjusting the clutch air gap and the automatic readjustment of the clutch air gap.
