RQA 125/SATS-2

Rotor Quality Analyzer

The RQA 125/SATS-2 Rotor Quality Analyzer is our most popular and advanced tester for quality control in manufacturing of squirrel cage rotors. It has been designed for use in a laboratory or industrial environment. This stand alone system is configured for automatic inductive and power measurement with manual loading and unloading of the rotor.

Features:

• Most sophisticated testing system for squirrel cache die cast rotors.
• Standardised by leading manufacturers of electrical motors and compressors world-wide.
• Wide range of application up to rotor OD of 125 mm.
• Optional tooling for testing of both – rotors with or without shaft.
• Fully automatic testing and evaluation cycle.
• Cycle time of approx. 6 sec. plus loading, allowing 100% testing of production series.
• Fostering SPC – In-process Monitoring and Correction.
• Easy set-up for different type of rotors to be tested.
• RQA-Win Software for Windows® including statistics and zoom.

Detectable faults:

• Broken or interrupted rotor bars.
• Cold soldered or missing connection between bar and end ring.
• Porosity either in the end rings or the rotor bars due to faulty injection processes, inferior aluminum alloy quality, and/or gaseous contamination.
• Insufficient oxidation between aluminum rotor bar and steel core resulting in the phenomenon known as soldering.
• Deviation of the rotor bar angle (skew).
• A short circuit between two or more rotor bars (fining).
• Eccentricity problems.
• Material inconsistencies in the aluminum alloy.
• Material inconsistencies in the steel core.
