Abstract: A method controls a motor, especially for opening and closing a door. The motor is controlled by a pulse width-modulated switching signal that is divided into a specifiable number of pulse width-modulated control signals for actuating a bridge circuit to a corresponding number of functional channels. The functional channels are switched off independently from each other by at least one or more switch-off signals on at least one switching circuit of a number of independent switching circuits corresponding to the number of functional channels.

Abstract: A method is disclosed for automatically determining an effective mass of a door system that is driven by a motor and has at least one door. In this case a speed change accomplished during an acceleration movement is established, and a force variable, for example the motor current or an armature voltage, influencing the drive force of the motor is summed or integrated during the acceleration movement. The effective door mass is established from the sum or the integral of the force variable and the speed change, the summation or the integration of the force variable being performed over a number of operating system cycles of a control device assigned to the door system. Also described is a control device for automatically determining the effective door mass, having a memory for force variable profiles that is designed in such a way that mass can be established for different force variable profiles in the memory in conjunction with an unchanged program code.

Abstract: Disclosed is a method for controlling an electrical door drive by means of which the door drive is switched off if the maximum torque is overshot and/or a defined nominal closing rate of the door is undershot as a result of the door drive being obstructed. In order to reliably prevent injuries and damage to people and objects in the event of a functional failure of the safety control system, and in order to nevertheless reliably block or reverse the door, it is proposed that pulse monitoring be carried out on the door drive, for redundant obstruction identification.

Abstract: The invention relates to a method for measuring a current that flows through a motor, in which a power switch that supplies the motor with electric energy is controlled by a control unit via a pulse width-modulation signal. The pulse width-modulation signal comprises a cycle of operation and the motor current is determined in a feeder to the power switch or a feeder to the motor. Since exactly one measured value representing the motor current is sampled in each cycle of operation, this permits the provision of a method for measuring the motor current, which determines the motor current in a more rapid, more cost-effective manner than in prior art. The method is used for the motor control of direct current motors.

Abstract: The invention relates to a door drive for an automatic door having a door panel, a brushless electric motor for generating the drive power and a belt or chain running in the opening and closing direction of the door for transmitting the drive power to the door panel. The door position is affected by a door position controller. An actuation device for controlling and/or regulating the electric motor includes an angle sensor for generating an angular signal proportional to the angle of rotation of the motor and a commutation circuit, for electronically commutating the motor, where the angular signal from the angle sensor is fed. The angular signal is also used as an input variable to the door position controller. The angle sensor is, in particular, an absolute value angle sensor working on a magnetic principle and designed for the unambiguous sensing of one complete revolution of the electric motor.

Abstract: A door operating mechanism for an automatic door is described, in particular for an automatic sliding and/or elevator door. A driving pinion or belt pulley for driving a belt or a chain which is used for transmitting the driving force generated by a motor to the door leaf is mounted to the shaft of the motor. The motor can be aligned with its shaft perpendicular to the opening and closing direction of the door. The door operating mechanism is of particularly compact design, even more so if the motor is an electronically commutated brushless synchronous motor and a magnetic angular encoder embodied as an absolute encoder and resolving 360° is used.
