Product introduction:  
  

I Introduction

YZZ principle axis three-phase induction motor specially designed for lathe industry based on consulting lathe practical operation performance index and absorption of advantages in domestic and overseas similar production. This kind of motor can be matched with various medium and top grade servo driver or transducer in domestic and overseas, operates open loop or close loop control, realizes operation in broad band, high speed and high precision controlled. Its preferencial accessory product for advanced numerical lathe product to enhance performance and level for its excellent machniery characteristic and tighten, beautiful appearance.

Good timing performance, excellent start performance both in low speed and high speed, outstanding characteristic in low vibration and low noise of motor in whole frequency range.

II Usage Features

1、High efficiency, high reliability, high overloading capability and high protection level.

2、Precise checking dynamic balance of rotor, high balance quality, low vibration.

3、Adopt import bearing with high precision, low noise.

4、Mandatory cooling by axis flow ventilator, strong wind, unique inner ventilation road to make sure motor can get effective cooling and limit resonance in any rotate speed so that implements long term operation in high speed or low speed.

5、Built-in overheating protection device in motor so that to cut off power supply when mortor unit reaches dangerous temperature to avoid damaging.

6、Beautiful appearance, reasonable structure, small volume, light.
