摘要 |
A programmable speed selector is provided for automatically adjusting the speed of a Reeves drive. The speed selector includes an output shaft which attaches to the adjustment crank shaft of the Reeves drive and a reversible motor having a drive shaft for driving the output shaft. Push button switches are provided to selectively energize the motor so that the drive shaft can be manually rotated to a plurality of different rotational positions. A sensing device is provided for sensing the direction and number of revolutions of the drive shaft during positioning thereof and a micro-controller is provided for learning the rotational positions and storing them into selected memory locations. Once programmed, the user may select one of the preset speeds on a key pad and the device will automatically control the motor to position the drive shaft in the desired position thereby automatically adjusting the reeves drive to a desired speed.
