Motor Winding Temperature Sensor

Wire wound rtds embedded in stator slots are the most common method for measuring winding temperature in large motors.

Motor winding temperature sensor.

The wire wound element extends through most of the body length and measures the average temperature of the winding. Thin film rtds are identical except for the size of the sensing element. These motor temperature sensors are sandwiched between the windings of motors generators. Interference of the signal can be eliminated with this function.

Flexible and stable monitoring with the option of easy and quick configuration. These sensor are sandwiched between the windings of motors generators. Ptc thermistors motor sensor is ceramic ptc thermistor pellet with insulated wire cable used for motor temperature sensing and over temperature protection by using ptc thermistor characteristics resistance rises sharply at curie temperature. How do you determine the operating temperature of a motor winding that does not have embedded detectors.

Unlike on off devices it allows continuous measurement of winding temperature. When connected to a keb vfd similar to a kty sensor the pt1000 sensor can display accurate real time temperature data of the motor. The measured and filtered temperature value is used for supervising and for monitoring the motor temperature. As you can see many common temperature sensors can serve as thermal winding protection devices for servo and induction motors.

The output temperature displayed is the hot winding temperature at the location of the sensor. Each lift station can have a number of temperature sensors which are monitored by the station operator. Unlike on off devices it allows continuous measurement of winding temperature. The stator winding temperature detector rtd are used to measure winding temperature of large motors generators etc.

Pt100 ω rtds measure the lift station pump and motor bearing temperatures and the motor winding temperatures are measured by cu10 ω rtds. If a handheld temperature detector were to read 129 c as in the example above the same concerns about the overall temperature would apply. Thermal winding protection and keb vfds. Install between stator windings for continuous protection of motors and generators class f or h single and dual element rtd s thermocouple elements available see our stock list below or call to inquire dimensions to fit any machine 1 3 and 12 channel temperature monitors to complete the system.

The time constant of the filter can be set with tempmfilt.
