Servo Gearmotor
The servo gearmotor was designed as the steering drive for a wheelchair.
The servo drive is made up of a standard series production wiper motor along with a successive spur gear motor. The actual position of the steering arm is transmitted by a potentiometer to the wheelchair steering control.
Manual movement of the steering arm changes the steering angle of the servo geared motor. If the steering arm is released, the wheelchair is automatically reprogrammed to move straight ahead.
The servo gearmotor has a manual override (free wheel activation) for use when pushing the wheelchair. When manual override for the servo gearmotor is activated, it is relayed to the electronic wheelchair control by a control switch in the gear. For safety reasons, the control then blocks the electrical power supply for motorized driving.
