Contact Motor

Contact Motor

YE3 series contact motor is independently developed by SIMO company. The coolant mode is IC411, which meets with regulations of GB/T 755 Rotating Electrical Machines- Ratings and Performance and JB/T 13299 Specifications for YE4-series (IP55) High Efficiency Three-phase Induction Motor (Frame size 63-355). Its efficiency value complies with the grade 2 energy efficiency standard in GB 18613-2020 and is consistent with the lE4 in the international standard IEC 60034- Energy Efficiency Grade of Single Speed Three Phase Cage Induction Motors. This series of products can completely replace the obsolete products of low-voltage three-phase asynchronous motors, such as Y, YGM, YGM2, YE2 and YE3-series of motor.

Low Voltage AC Motor

 

Brief Introduction

What is angular contact motor ball bearing in low voltage ac motor

Angular contact ball bearings can withstand both axial and radial forces in one direction simultaneously. The line connecting the two points above and below the force point of the rolling element has a certain angle with the radial direction. This type of bearing is an angular contact bearing.

 

What types of bearings do angular contact ball bearings in low voltage ac motor belong to

1. Angular contact bearings belong to the category of ball bearings in rolling bearings

2. Due to its ability to withstand both radial and certain axial forces, angular contact bearings are often installed in pairs, with back-to-back or face-to-face forms,

3. There are two types of angular contact bearings: integral and separable. During installation, a certain axial force is generally required to eliminate bearing clearance. Therefore, bearings generally do not provide clearance

 

What is the difference between angular contact motor ball bearings and self-aligning ball bearings
Angular contact ball bearings can withstand both radial and axial loads simultaneously. Capable of operating at higher speeds. The larger the contact angle, the higher the axial bearing capacity.

 

Due to the relative displacement of the inner and outer raceways on the horizontal axis, they can withstand both radial and axial loads - combined loads (single row angular contact ball bearings can only withstand unidirectional axial loads, so they are usually installed in pairs).

Due to the spherical surface of the outer ring raceway, self-aligning ball bearings have self-aligning performance, which can automatically adjust the misalignment caused by the deflection or non concentricity of the shaft or shell. Conical hole bearings can be easily installed on the steel plate stamped cage on the shaft by using fasteners

 

The inner wheel and steel ball can tilt freely towards the outer wheel, so a certain degree of assembly error (misalignment) or radial curvature of the shaft can be automatically adjusted without damaging the bearing of contact motor.
