电机温控保护系统
摘要：
本实用新型公开了电机温控保护系统，包括温度控制器、报警器，所述温度控制器一方面通过温度传感器与电动机连接，另一方面通过报警电路与报警器连接。还包括联锁电路，所述联锁电路一方面与温度控制器连接，另一方面与电动机连接。本实用新型是在电机轴承或机身合适部位安装一个或多个小型温度传感器，将温度信号实时传送到温度控制器，在温度控制器中可以设定报警温度及联锁温度。当到达报警温度时温控器输出信号驱动报警装置（如警铃、灯光等）。当到达联锁温度时温控器输出信号与电机控制系统联锁，使电机停机，保护电机不至于烧毁。
摘要（英）：

The utility model discloses a motor temperature control protection system. The motor temperature control protection system comprises a temperature controller and an alarm and further comprises an interlock circuit, wherein the temperature controller is connected with a motor through a temperature sensor and is further connected with the alarm through an alarm circuit, and the interlock circuit is connected with the temperature controller and is further connected with the motor. According to the motor temperature control protection system, one or more micro temperature sensors are mounted on a motor bearing or proper positions of a machine, so a temperature signal can be transmitted to the temperature controller in real time, alarm temperature and interlock temperature can be set in the temperature controller. When temperature rises to the alarm temperature, the temperature controller outputs a signal to drive the alarm device such as an alarm ring or light; when temperature rises to the interlock temperature, the temperature controller outputs a signal for interlock with a motor control system to stop the motor, so the motor is protected from being burned out.
