Abstract
A new method and circuit arrangement for operating an electric motor, such as a stepper motor, in a control loop for preventing motor stall, the electric motor comprising at least a first motor coil and a second motor coil, the method comprising: operating the electric motor at a velocity equal to the target velocity; receiving a load value associated with an electric motor load; and determining whether the load value is greater than a load value threshold. Based on a determination that the load value is greater than the load value threshold decreasing the velocity of the electric motor to a velocity less than the target velocity.
