Speed Motor

The speed motor maintains a requested relative Wheel/Crank speed using bounded torque.

control.set_speed_motor(options)
control.get_speed_motor()

Example#

wheel = jolt_control_wheel({speed_motor: {speed: 120, max_torque: 5}});
var request = wheel.get_speed_motor();
request.speed = -60;
wheel.set_speed_motor(request);
// Torque-limited brake:
wheel.set_speed_motor({speed: 0, max_torque: 5});
// Release the motor:
wheel.set_speed_motor({enabled: false});

speed is a target; get_speed() returns actual speed. Zero actively brakes; enabled:false releases the drive. The motor does not directly overwrite body velocity, so insufficient torque causes slowing or stalling under load. Relative speed is measured against the parent, or the world.

Verified operation contracts#

These contracts distinguish units, return values, errors and lifetime according to the current implementation. Check results: false, 0 and undefined can mean different things for different methods.
