Powered skate with automatic motor control
First Claim
1. A system for controlling powered skates, the system comprising:
- a pair of powered skates, each comprising;
a foot platform configured to receive a foot of a rider;
a plurality of wheels coupled to the foot platform;
a hub motor integral to at least one of the plurality of wheels, the hub motor configured to rotate the at least one wheel; and
a load sensor coupled to the foot platform and configured to sense an applied force; and
a controller coupled to each of the hub motors and to each of the load sensors, the controller configured to cause each of the hub motors, using a single algorithm, to generate a forward torque based on signals received from each of the load sensors.
