Definitions
- Power supply device for an electric motor method for operating an electric motor
- the invention relates to a power supply device for a normal operation and / or in an emergency operation operable electric motor, in particular for an actuator in a motor vehicle, and a method for operating an electric motor in a normal operation and / or emergency operation, in particular for an actuator in a motor vehicle.
- a three-phase asynchronous motor is an electric motor that is operated with three-phase current. Seen electrically, an asynchronous motor is a short-circuited three-phase transformer whose secondary winding (a rotor) is rotatably mounted. By an operating voltage applied to a stator winding, a rotating magnetic field is generated inside the machine, which induces a current in the short-circuited inner winding (armature). This current itself builds up a magnetic field around the rotor. Both magnetic fields interact in such a way that ultimately a torque is generated.
- a three-phase synchronous motor is an electric motor, which is also operated with three-phase current. He has outside a winding that generates a magnetic rotating field.
- the rotor carries either permanent magnets or a field winding for field generation.
- the rotor with the excitation hurries in the synchronous motor to the rotating field.
- the synchronous machine has no slip, in contrast to the three-phase asynchronous motor, since no voltages must be induced in the rotor. Therefore, you can rely on their operation at the rigid network to their constant speed.
- the electric motors are usually controlled electronically using electronic control devices, wherein operating states (system states) of the controlled by means of the electric motor to be controlled and / or the actuator to be adjusted system are monitored. If the monitored operating states are within certain, specifiable limits, the monitored system operates in a state usually designated as the normal state.
- control device generally provides a control for emergency or emergency operation in order to avoid damage to the controlled system ,
- Such an emergency operation may be, for example, an adjustment of the adjustable by the actuator component in a safety position, also referred to as fail-safe position.
- a safety position also referred to as fail-safe position.
- Known here is, for example, an electronic camshaft adjustment in a motor vehicle internal combustion engine, in which the electric motor of the actuator is disconnected from a controller in an error and the electric motor, the camshaft - if possible with a target target speed - adjusted so in the fail-safe position that the internal combustion engine can be operated at least still with emergency running properties.
- the approach of the fail-safe position or the adjustment in the fail-safe position can be effected for example by a return spring on the actuator.
- the disadvantage of this is that the return spring leads to an oversizing of the adjustment.
- Another disadvantage is that in normal operation, the (electric) motor has to overcome the spring force, which leads to a higher load during normal operation and / or higher drive costs of the adjustment.
- the approach of the fail-safe position can be further effected for example by a second parallel (electric) motor.
- a second parallel (electric) motor is associated with a high technical overhead and / or considerable additional costs.
- the fail-safe position can also be effected, for example, by short-circuiting the (electric) motor, which causes the motor to brake.
- the braking principle Siert on an induced back voltage of the engine and is therefore speed-dependent. At lower speeds no braking torque is available, which keeps the adjustment system in the fail-safe position, if this is achieved.
- the applicant here reserves the right to divulge the above security concepts for the achievement of fail-safe positions from the present application and to pursue them further in the context of divisional applications as independent objects.
- the object is achieved by a power supply device for a normal operation and / or in an emergency operation operable electric motor and by a method for operating an electric motor in a normal and / or emergency operation with the features of the respective independent claim.
- the power supply device for an electric motor operable in a normal operation and / or in an emergency operation, in particular for an actuator in a motor vehicle, has a power supply unit, by means of which the electric motor can be supplied with three-phase current in the normal operation.

- a motor vehicle actuator When the electric motor is being decelerated, a motor vehicle actuator is particularly preferably moved to a safety position, in particular an emergency running position or a fail-safe position.
- the braking torque and thereby the travel or adjustment speed is thus directly dependent on the current flowing in the phases.
- the motor vehicle actuator is held in the safety position by the non-rotating and / or stationary magnetic field and / or by the braking torque generated thereby. Maintaining the safety position over time is expedient to ensure with a minimum power consumption, in order to minimize the energy consumption, to optimally adjust the braking torque and to protect the electric motor against overtemperature.
- the current consumption ie the direct current and / or thus the braking torque, with which the electric motor can be braked is, and / or a travel speed when moving the motor vehicle actuator into the safety position, is adjustable.
