A-1737

A-1737 Motor Coil Temperature Sensor This sensor is used on a starter generator to provide temperature measurement of the motor coil. Typically mounted on the neutral bar, it detects increases in current that would indicate a failure that could lead to a stall. The sensor can also be used to monitor the motor windings temperature and warn of an over-temperature condition. Applications Features • EV / HEV motor coil • High accuracy and long term stability • HVACR motor protection • Existing field proven design • Industrial automation and control • Weld connections covered by PTFE Heat Shrink • Meets the temperature and vibration demands of EV and HEV traction motors • Alternate RvT (resistance versus temperature) curves available • Custom packages available to meet various motor configurations. • A variety of terminal and connector options Amphenol Advanced Sensors Specifications R @ 25°C 30,000 ohms ±5% R @ 210°C 155.45 ohms ±11.5% B (25/85) 3974 Operating Temperature Range -40°C to 210°C Storage Temperature Range -40°C to 225°C Temperature Accuracy 1.53°C at –40°C 1.25°C at 25°C 6.23°C at 210°C Response time 7 seconds liquid to liquid Housing Material Axial leaded glass NTC thermistor Resistance vs. Temperature Data Terminal Resistance = 30000 Ohms at 25 °C Rtol. @ 25°C 5.0% Molex Terminal 33011-3001 Temp.
