Brief Introduction

The temperature rise of YE5 series three phase traction motor stator winding shall be carried out by the following regulations:

1. The motor adopts 155(F) class insulation. When the on-site altitude and ambient temperature are in line with regulations of the standard, the temperature rise of motor stator winding should be assessed with 80K (resistance method), and the temperature rise value revise interval should be 1. If altitude and ambient temperature in the testing station are different from those in regulations of the standard, the maximum of temperature rise should be adjusted in accordance with regulations in GB/T 755-2008.

2. When measuring the winding temperature with resistance method, motors should be stopped at the end of thermal test. If the figure can be read at the first time of the interval in regulations when the motor is powered off, the temperature rise calculated does not need to extrapolate to the instant of power failure. If the figure can not be got at once, the allowable temperature of motor bearing should not exceed 95℃ according to GB/T 755-2008 standard.

3. When the motor is hot and its torque is increasing, it should be able to withstand the specified maximum torque (including tolerance), a short-term over-torque test lasting 15 s without speed mutation, stall and harmful deformation. At this time, the voltage and frequency should be maintained at the rated value.

4. Motors with rated power of 315 kW and below should be able to withstand 1.5 times rated current, lasting no less than 2 minutes of accidental overcurrent test without damage.

5. For the safe operating speed of the motor, unless otherwise marked on the nameplate, all motors with frame number 315 and below shall be able to operate safely and continuously within the speed listed in GB/T755-2008.
