Broken Bar Rotor Testing Machine For Electric Pump Rotor

1. Introduction

• Station: single
• Test item: number of conducting bars, number of broken bars, number of thin bars, slot deviation angle
• The machine and test bench are separated, which is suitable to test rotors with different size, and it is convenient to be moved.

2. Test specification

• Dimension range: outer diameter 60-130mm, inner diameter 10-50mm, lamination thickness 180mm(max).
• Test item: number of conducting bars, number of broken bars, number of thin bars.
• Test parameter: the quantity of bars, minimum value, maximum value, comprehensive value.
• Fixture mode: manual/auto

3. Feature

• Strong compatibility: the separated test bench design makes the machine can test rotors with different size.
• Full function: the machine can test broken bar caused by manufacturing process, and it can improve the quality of rotor control completely.
• Test fast: it takes 5 seconds to complete all the tests and output the result (not include the fixture time)
• Rotor testing machine support connection with all kinds of MES system.
• Built-in IPC can save a large amount of data, and it is convenient to export data via USB port.
• Simple interface: professional test software developed based on the window XP, more understandable and humanized interface.
• The quality of squirrel-cage rotor affects the performance of motor, and the quality of aluminum rotor depends on the technology parameter, rotor iron core, the preheating temperature of molding, aluminum liquid water and chemical components.
• The problems of broken bar, thin bar and porosity occurs frequently in the production line, and these problem will increase the rotor resistance, consumption and bring out low motor efficiency, high temperature rise and high slip ratio.
