This is a wheelchair motor and with spur gearbox and optical encoder. If you want this motor without the encoder, follow this link. They make great motors for heavy-duty robots, providing higher payload capacities, power, and performance. The encoder feedback makes this motor an excellent choice for an autonomous robot. Unlike many wheelchair motors, these do not have a left and right hand version and are sold individually. We have tested a lot of motor and gearbox combinations and these work very well for our purposes.

We use US Digital Encoders on these motors when the option is selected below.
