Y Series three-Phase asynchronous Motors
Basic introduction
Y series motors are low-voltage three-phase asynchronous motors, that are primary series for standard function. This series motors can meet needs for standard purpose interiorly and overseas with frame vary from 80 to 315. This series motors built in accordance for the national unified normal.
Y series motors have the benefits of higher efficiency, energy saving, excellent operation functionality, compact vibration, decrease noise, lengthy services lifestyle, high dependability and easy servicing. Mounting dimensions along with the power grade totally conform to IEC common. They’re in class B insulation, IP 44 degree for protection and cooling mode of IC411. The rated voltage and frequency of Y series are respectively 380V and 50HZ. Y 
connection is adopted for motors beneath
3KW (3KW incorporated) and connection is adopted for those above 4KW( 4KW included).
Y series motors are usually applied in machinery products without the need of any particular requirement.
YD Series multi-speed three-Phase asynchronous Motors
Standard introduction
This series motors are designed and produced beneath incorporating the benefits of the around the world counterparts, and therefore are in complete conformity with international regular of IEC. This series motors employed the technique of modifying the pole numbers to perform velocity adjustment to ensure that they have outstanding options like modest volume, lighter weight, minimal noise, well starting efficiency, reputable operation, effortless maintenance, etc. The main technical indexes have reached the international technical standard.
The series motors are broadly utilized in several mechanical gear which have to have stepped pace adjustment; It allow the equipments to have compact structure, decrease noise and capacity of vitality conserving.
Simultaneously, multi-speed motors with special specification is usually developed and manufactured in accordance towards the needs of customer, such as multi-speed three-phase asynchronous motor for YDT supporters and pumps. Degree of safety: IP44, or IP54, or IP55; Rated voltage: 380V, rated frequency: 50HZ.
