PC Based Rotor Tester – 4008RJ
About the 4008RJ
The 4008RJ PC Based Rotor Tester is a reliable, fast, and cost-effective system designed to detect rotor faults in less than 10 seconds.
Unlike the GTS 1000 (large rotor testing), the 4008RJ is specialized for small-sized rotors, with a stack length under 300 mm and a weight capacity up to 10 kg.

Rotor Fault Detection
The 4008RJ operates using induced currents in rotor bars while rotating in a permanent magnetic field. A probe captures these signals and displays synchronized sinusoidal waveforms for fault analysis.
Detectable Rotor Faults:
-
Broken or interrupted rotor bars
-
Poor or missing connections to rotor end rings
-
High bar resistance
-
Short circuits between bars
-
Errors in commutator-to-slot positioning
-
Non-uniform lamination in commutator
-
Skew angle deviation
✅ Applicable for both Aluminium & Copper Die-cast Rotors
