Definitions
- the invention relates to a method for operating an asynchronous machine having a rotatably mounted rotor and a stator fixed to the housing, wherein a torque of the asynchronous machine by specifying a desired magnetic flux of a rotating magnetic field of the stator and by
- Presetting a desired slip between a rotor speed of the rotor and the rotational speed of the rotating magnetic field is set.
- the invention relates to a corresponding device for operating an asynchronous machine, which has a rotatably mounted rotor and a
- the means for adjusting the torque specifies a desired magnetic flux of a rotating magnetic field of the stator and a target slip between a rotor speed of the rotor and the rotational speed of the rotating magnetic field.
- the invention relates to a corresponding asynchronous machine.
- asynchronous machines depend on two variables, the magnetic flux of the magnetic field circulating around the stator and the slip between the rotor speed and the "rotational speed" of the rotating magnetic field
- a desired slip is so set that a rotational frequency of the rotating magnetic field
- the setpoint value of the rotational frequency of the stator field can be calculated to be 0 Hz, while a significant current flows through the stator.
- a limit for the operation of power electronics or the asynchronous machine driving device is the thermal capacity of the switching elements or circuit breaker.
- Machine for example, is still zero.
- the method according to the invention provides that, at least in a load case, alternatively whenever a target rotational frequency of the rotating stator of the stator is zero, the desired magnetic flux and / or the desired slip at constant torque are changed such that the Actual rotational frequency of the rotating magnetic field is not equal to zero, so that a minimum rotational frequency greater than zero is achieved.
- This is achieved in a simple and cost-effective manner, that the stator is not performed by a single circuit breaker for a long period of time, but alternately by different circuit breakers, whereby the power electronics is protected from thermal overload.
- the initially calculated set rotational frequency is correspondingly changed or not set to zero, or that the target rotational frequency, for example, an offset value is added, which leads to a corresponding rotational frequency.
- the setpoint slip is reduced while the torque remains the same and the setpoint magnetic flux, which is proportional to the stator current, is increased.
- the desired minimum rotational frequency of the circulating magnetic field is achieved with constant torque by reducing the desired slip and increasing the desired magnetic flux, which is proportional to the stator current.
- the desired minimum rotational frequency of the circulating magnetic field is achieved with a constant torque by increasing the desired slip and reducing the desired magnetic flux.
- the method according to the invention is carried out in a generator operation of the asynchronous machine.
- Asynchronous machine can be reduced overall.
- the device according to the invention with the features of claim 5 is characterized in that the device in the load case when the target rotational frequency of the rotating magnetic field of the stator is zero, the desired magnetic flux and / or the desired slip at constant torque changed so in that the actual rotational frequency is not equal to zero.
- the setpoint slip is reduced while the torque remains the same, and the desired magnetic flux is increased in order to bring the actual rotational frequency to a value not equal to zero. This will cause uneven thermal loading of circuit breakers of the device or the power electronics and motor phases bypassed. The performance or performance of the asynchronous machine is not affected.
- the setpoint slip is increased while the torque remains the same and the setpoint magnetic flux is reduced to the desired one
- the device has a bridge circuit, in particular a B6 bridge with six circuit breakers, in particular semiconductor switching elements or power semiconductor switches.
- Figure 1 shows an asynchronous machine in a simplified representation
- FIG. 2 shows an advantageous method for operating the asynchronous machine.
- FIG. 2 shows in a flowchart a method for operating an asynchronous machine 1, as illustrated by way of example and simplified in FIG. 1, which has a stator 2 fixed to the housing and a rotatably mounted rotor 3 and a device 4 for operation.
- the device 4 the
- Implementation of the method includes, inter alia, a device which is designed as power electronics 5, and in particular by specifying a desired magnetic flux of a rotating magnetic field of the stator and by specifying a target slip of the rotor, ie a difference between the rotor speed and speed of circulating magnetic field, a torque of the asynchronous machine 1 sets.
- the power electronics have a B6 bridge or bridge circuit which has six power semiconductor switches.
- the procedure provides that after commissioning a the
- Asynchronous machine 1 having drive device in a first step S1 first the desired torque is detected in a step S2.
- the setpoint magnetic flux and the setpoint slip are set in step S2.
- step S3 it is determined to which target rotational frequency the predetermined nominal magnetic flux and the predetermined nominal slip of the circulating magnetic field lead.
- a load case that is, for example, a torque request and the speed of the electric machine is equal to zero
- the determined target rotational frequency is checked whether it is equal to zero or not equal to zero.
- small deviations from zero are preferably also rated as zero value.
- the setpoint slip and / or the desired magnetic flux are changed in a step S6, wherein the desired torque determined in step S2 is maintained.
- the setpoint slip is reduced somewhat and the stator current, which is proportional to the desired magnetic flux, is increased somewhat.
- the desired slip can be increased and the desired magnetic flux can be reduced.
- the method is carried out when the asynchronous machine is operated as a generator.
