Definitions
- the invention relates to an electric motor with a device for temperature monitoring.
- each electric motor that is fed by a converter is usually monitored with regard to its operating temperature.
- Corresponding temperature monitoring is generally carried out by means of temperature sensors, the sensors of which are located in the immediate vicinity of the windings of the electric motor, the temperature sensors having specific temperature / resistance characteristics. As a rule, such
- Temperature sensors have an increased resistance value with increasing operating temperature, which corresponds to a positive temperature coefficient of the temperature sensor. With the help of the temperature sensors, both temperature monitoring and temperature triggering in the electric motor can be implemented.
- the temperature monitoring uses a unique assignment of a temperature value detected by the sensor to a specific resistance value.
- a temperature trip can be viewed as a thermal switch that triggers when a certain threshold is reached and the
- Temperature monitoring are not compatible.
- buyers of converter-operated electric motors are often forced to select the respectively compatible control device with regard to the temperature sensor, or to make complex adaptations of a temperature monitoring sensor system of the electric motor
- Temperature sensors with different temperature characteristics to accept a sensor characteristic of temperature sensor inputs of the control device.
- the object on which the present invention is based is therefore to provide an electric motor with a device for temperature monitoring which, in a simple and convenient manner, allows control devices with a wide variety of temperature sensor input characteristics to be connected.
- a device for temperature monitoring in an electric motor has at least two temperature sensors with different temperature characteristics.
- the temperature sensors are connected to terminals on the electric motor by means of electrical cables. It is advantageously possible, by simple, individually selectable interconnection of temperature sensor inputs of the control device with the connection terminals on the electric motor, to operate the electric motor with control devices with a wide variety of temperature sensor input characteristics.
- the electric motor according to the invention advantageously comprises temperature sensors with a temperature monitoring characteristic and / or temperature sensors with a temperature tripping characteristic.

- These include, for example, so-called service-mounted network resistors (SMN resistors) as specially designed thermal resistors with a positive temperature coefficient and switching characteristics. With the help of such. SMN resistors make it possible to monitor three phase windings of the electric motor for thermal tripping.
- the characteristic curve of the SMN resistor has a defined switch-off point which is connected to a control device connected to the electric motor. which has temperature sensor inputs with SMN resistance characteristics, is transmitted.
- FIG. 2 shows an exemplary embodiment of an interconnection of a control device 4 with the electric motor 2 according to the invention.
