| 摘要 |
The invention is a driving mechanism for exerting a pre-determined torque characteristic, comprising a stepper motor (12) having a motor shaft, a rotation measuring device detecting the angular position of the motor shaft (14), a motor control unit effecting the torque characteristic on the basis of the angular position of the motor shaft (14), a drive shaft (10) exerting the torque characteristic and an essentially backlash-free transmission connecting the drive shaft (10) with the motor shaft (14), and the motor control unit is a local motor control unit providing operating signals to the stepper motor (12) and being programmable in at least one parameter. |

1. A driving mechanism for exerting a pre-determined torque characteristic, comprising
a stepper motor (12, 36, 56) having a motor shaft (14, 14′, 14″, 34, 52), a rotation measuring device detecting the angular position of the motor shaft (14, 14′, 14″, 34, 52), and a motor control unit effecting the torque characteristic on the basis of the angular position of the motor shaft (14, 14′, 14″, 34, 52), characterized by comprising a drive shaft (10, 10′, 10″) exerting the torque characteristic and an essentially backlash-free transmission connecting the drive shaft (10, 10′, 10″) with the motor shaft (14, 14′, 14″, 34, 52), and the motor control unit is a local motor control unit (58) providing operating signals to the stepper motor (12, 36, 56) and being programmable in at last one parameter. |
