The motor is running in the Notes

Electric Motor design are generally at an altitude of no more than 1000m, ambient air temperature does not exceed 40 ℃ place to run. Auto extra voltage ± 5% or less variation, fixed-rate, can be rated for continuous operation. If the voltage is less than ± 5%, then the manufacturer should be required or limit load test results. Operation of the motor temperature should follow the manufacturer's requirements. Short-term fixed car, the temperature limit of its components, so that more value is specified in Table 1-2 to improve 10K.

Permissible bearing temperature 80 ℃ (when the oil temperature does not exceed 65 ℃). Allows the bearing temperature 95 ℃ (ambient temperature does not exceed 40 ℃). If the Hydraulic motor runs at the highest ambient temperature of 40 ℃ to 60 ℃, temperature limits should not exceed 40 ℃ ambient temperature value decreased. If the motor temperature 0 ℃ to 40 ℃ (for example, T ℃) between the temperature limit is generally not increased. Later, when the manufacturer agreed to allow an increase (40 - T) K, but the biggest 30K. Frequent full pressure start induction motor, heating should pay particular attention to their situation.

The motor cooling air from the outside to prevent moisture in the stands, you must immediately stop the supply of cooling air. Check the spark is normal brushes, the slip ring (or turn) with burns and abrasion. Check that the Electric Motor is running an unusual noise and vibration, stator and rotor relative friction.
