The Motor is a Hand, and thus can bind and unbind from fibers.
A bound Motor can move along its fiber. The direction of the motor is set by the sign of max_speed. If the speed is positive, the motor attempts to move towards the PLUS_END.
The speed is linearly proportional to the load of the motor. The load is the projection of the force vector on the direction of the fiber.
The actual movement is calculated from the time step:
As defined in Hand, detachment increases exponentially with force.
See Examples and the Parameters of Motor.
