High Efficiency Motor

Title

High Efficiency Motor

Brief Introduction

The value to be adopted for the temperature of a coolant during a test shall be the mean of the readings of the temperature detectors taken at equal intervais of time during the last quarter of the duration of the test . To reduce errors due to the time lag of the change of temperature of large machines following variations in the temperature of the coolant , all reasonable precautions shall be taken to minimize such variations .

The temperature of the ambient air or gas shall be measured by means of several detectors placed at different points around and halfway up the machine at 1 m to 2 m from it . Each detector shall be protected from radiant heat and draughts .

Open YE3 motor and motors cooled by air or gas from a remote source through ventilation ducts and machines with separately mounted heat exchangers.

The temperature of the primary coolant shall be measured where it enters the machine .8.3.4.4 Closed machines with machine - mounted or internal heat exchangers The temperature of the primary coolant shall be measured where it enters the machine . The temperature of the secondary coolant shall be measured where it enters the heat exchanger .

The temperature rise ,A0, of a part of a machine is the difference between the temperature of that part measured by the appropriate method in accordance with 8.5, and the temperature of the coolant measured in accordance with 8.3.4.
