，
MY series aluminum housing 1.5 hp electric motor single phase 3450 rpm, with run capacitor, is made of selected quality materials and conform to the IEC standard. MY motors have features of good performance, low noise, little vibration and safety and reliable operation. The multiple of starting torque is 0.3-0.7 (MY), 0.45-0.75 (MYT). MY motors are suitable for the occasion where there requirements of starting torque is low and long-term continuous working, such as home electric appliances, pumps, fans, and recording meters, etc.

Causes of mechanical noise produced by three-phase asynchronous motors
①The ②～⑥ of the reasons for the larger no-load loss are basically applicable to this item, which is the main reason for the large bearing noise.
② ⑦ among the reasons for the large no-load loss is the reason for the large ventilation noise. In addition, the fan blade angle or size of the axial fan is not correct, the design of the air path (including the exterior and the interior of the three-phase motor) is unreasonable, or there are obstacles in the air path, etc., will increase the ventilation noise (at this time, a similar whistle is often emitted Noise). Block the air inlet hole of the wind hood with cardboard, that is, cut off the air inlet. If the noise is significantly reduced, it can be determined that this is the cause.
③Some parts are not installed in place or loose.
④The stator and rotor or some relative moving parts (eg: bearing seal ring, oil baffle, water sling ring, etc.) may cause mutual friction due to improper installation, excessive looseness, or tightness.
⑤For the variable frequency motor powered by the frequency converter, the same as the item ⑤ with large vibration
