Abstract

The invention provides a motor high temperature alarm and a method implementing high temperature alarm. The motor high temperature alarm includes a bridge circuit containing a platinum resistor and used for generating a corresponding first voltage by utilizing between-bridge-arm resistance unbalance caused by change of the resistance value of the platinum resistor; the platinum resistor embedded in a target position, used for monitoring the temperature of the target position and generating resistance change when the temperature of the target position changes; a voltage amplifier used for amplifying the first voltage output by the bridge circuit and outputting the amplified first voltage to a voltage comparator; the voltage comparator used for determining voltage threshold value, comparing the amplified first voltage with the voltage threshold value and triggering an alarm module for high temperature alarm when the amplified first voltage is greater than the voltage threshold value. The scheme provided by the invention can improve high temperature alarm accuracy effectively.

Description

technical field [0001] The invention relates to the technical field of control, in particular to a motor high temperature alarm and a method for realizing the alarm. Background technique [0002] In the industrial production process, the motor in the equipment is often caused by the failure of the cooling system or heat dissipation system and other parts, resulting in excessive temperature of the motor. If the motor continues to operate at high temperature, the oil quality will change and the oil film will be damaged, which will cause damage to the motor. Therefore, high temperature alarm for the motor is one of the ways to avoid continuous operation of the motor at high temperature. [0003] At present, the main method of motor high temperature alarm is to embed a temperature sensor on the motor casing. When the temperature of the motor casing reaches a certain value, the temperature sensor will send out an alarm after sensing. The existing temperature sensor can only sens...
