Description

125800-01 Electrodynamic Velocity Sensor


The 125800-01 electric motor is an essential part of any industrial application. You could say that it is one of the most important, if not the most important, element of any production process. Of all the different motor types, induction motors are the most commonly used. However, you can find all types of motors in different parts of the process.

The 125800-01 fully supports the Atmel Studio 7 IDE, the STK600 platform and Atmel Startup, a free online tool to configure peripherals and develop software. Three microcontrollers are available for sampling and mass production.

A QFN24 package is available for 10k units.
The Artini 1616 is available in a QFN20 and SOIC20 package for 10k units.
The Artini 1614 is available in a SOIC14 package for 10k units

125800-01 Temperature is one of the most important operating parameters of electric motors. Motor heating is caused by mechanical, electrical and copper losses, as well as by heat transfer to the motor from external sources such as ambient temperature and surrounding equipment. If the temperature of the motor windings exceeds the maximum rated temperature, the windings can be damaged and the motor can be damaged and insulated and may crash or fail completely. This is why most electric motors, especially those used in industrial processes, have a temperature sensor integrated into the motor windings.

 

The 125800-01 sensor monitors the winding temperature directly and is used in conjunction with a protection circuit to prevent damage caused by excessive temperatures. The sensor shows a predictable and precise change in resistance as it experiences temperature changes. As the temperature increases, the resistance increases (e.g. Kty) or decreases (e.g. NTC thermistor). The change in resistance is almost linear in most types, such as KTY, t100 and tT1000. Sometimes the resistance changes in a non-linear way, such as with NTC, but in any case, using one of these sensors will allow us to continuously monitor the temperature of the motor windings.
