METHOD FOR DETECTING STALLING OF AN ELECTRIC STEPPER MOTOR, AN ELECTRIC STEPPER MOTOR AND A HEATING, VENTILATION AND/OR AIR CONDITIONING SYSTEM WITH AN ELECTRIC STEPPER MOTOR
METHOD FOR DETECTING STALLING OF AN ELECTRIC STEPPER MOTOR, AN ELECTRIC STEPPER MOTOR AND A HEATING, VENTILATION AND/OR AIR CONDITIONING SYSTEM WITH AN ELECTRIC STEPPER MOTOR
A Method for detecting stalling of an electric stepper motor (18), with the following steps is shown:a) samples of the voltage at a coil of the stepper motor (18) are taken continuously or in regular intervals,b) a deviation value is determined corresponding to the deviation between the measured voltages of the two samples, andc) the deviation value is used to determine whether the electric motor (18) is stalling.;Further, a stepper motor and a heating, ventilation and/or air conditioning system is shown.
