Abstract (en)
[origin: EP1894877A2] The drive has a brushless direct current motor (10) e.g. permanently-excited synchronous motor, generating drive power, and a belt drivewheel (12) controlling a tough toothed belt (16) that transmits the power to the door panels (2, 3). An actuation device controls the motor, and comprises a digital magnetic absolute value sensor for generating an angular signal proportional to an angle of rotation of the motor. A commutation circuit commutates the motor, to which the signal from the sensor is fed, where the signal from the sensor is fed to a door position controller as an input variable.
