Megohmmeters (meggers) are electrical meters used to check the resistance and condition of the motor windings and the condition of the refrigeration and oil environment around the motor windings. A ...

Check for any burned odor smell that might be emanating from the motor windings that could suggest overheating. Inspect the relay and contacts as well. Generally, not only should the motor be ...

The winding configuration also minimizes effects from outside disturbances and lets the motor reach peak force in 700 msec. The compact motor relies on permanent rare-earth magnets and three-phase ...

Some of the more common configurations in three-phase motor windings are the Wye and Delta configurations (See Figure 1). By measuring voltages between line 1 to line 2, line 2 to line 3, and line 3 ...

in Finland has constructed the world’s first prototype electrical motor using carbon nanotube yarn in the motor windings. The new technology may significantly enhance the performance. Engineers of LUT ...

HIOKI recently announced the launch of the Impulse Winding Tester ST4030, which is the company’s first instrument to provide functionality for testing for defects in motor windings. HIOKI ...

Since there are no windings or slots, the motor generates no slot harmonics and no ac excitation of any noise, so they run quiet. There is no iron in the coil, so there is no cogging or hysteresis ...

This creates a shorter end-turn space, thereby reducing heat and improving torque and power density, as well as reducing motor size. The winding scheme also makes it easier to strengthen the ...
