Abstract
The invention relates to a control device for a motor for adjusting a control unit. A motor (5) that serves for adjusting a control unit (20) is shut off in a known control device with at least one Hall switch, when the control unit (20) has achieved a desired position. In the aforementioned variant, it is proposed that the running direction of the motor (5) is determined by a signal (UH) obtained from such a Hall switch, and, if necessary, the motor (5) is prepared for reversal.
Claims13
1. A control device for a motor for adjusting a control unit having a shaft, wherein the motor and the control unit are functionally connected, comprising:
- (a) a magnet disposed on the shaft of the control unit;
- (b) at least one Hall switch disposed to create at least one first signal (UH) upon displacement of the magnet, wherein the first signal (UH) presets a running direction of the motor;
- (c) a logic circuit having an output, and having first and second inputs, and disposed to receive an adjustment signal (UST) in the first input and the first signal (UH) in the second input;
- and
- (d) a bridge end switch operably connected to receive the output of the logic circuit and having an output operably connected to the motor;
- and
- (e) wherein the bridge end switch is so connected with the logic circuit and the motor that when the first signal (UH) is compared with the adjustment signal (UST) in the logic circuit, a corresponding control signal for the motor is output from the output of the bridge end switch.
