Short description
The Rotor-Check 400 LM-MP-RC400 is a compact test instrument for characterizing the magnetic field strength curve of rotors. The unit and its measuring probe connect to a Windows PC via USB and work with the RotorCheck software to record, analyze and export measurement curves.

Application information

• Radial and axial measurements on magnet rotors
• Evaluation of magnetisation and magnet quality
• Detection of assembly errors in lamination stacks
• Analysis of core inhomogeneities and pole irregularities
• Determination of lamination stack position relative to the shaft
• Detection of stray-field magnetisation and local/global pole peaks

Operation
An accurate high-resolution stepper motor rotates the rotor up to 360°. The measuring probe is maintained at a constant distance by a height-adjustable mount to ensure comparable readings during rotation. The rotor shaft thickness supported is up to 13 mm and the probe reach is adjustable up to 12 cm. Rotation speed is selectable in three modes to trade off time and sampling density: 90 s = 1000 points, 45 s = 500 points, 23 s = 200 points.
