RMO M Series Motor & Generator Winding Ohmmeters
The Motor & Generator Winding Ohmmeter instruments are designed to measure winding resistance of electrical motors and generators. Based on the state of the art technology, using the most advanced switch mode technology available today, RMO-M series instruments are: accurate (0,1%), powerful (up to 100 A) and lightweight (8,0 kg / 17.6 lbs). Instruments generate a true DC ripple free current with automatically regulated measurement and discharging circuit.
RMO-M series instruments can perform a simple, quick, and reliable DC resistance measurement of all types of rotating machine windings. Problems such as a turn-to-turn short circuit in a winding, which reduces a motor / generator's ability to produce a balanced magnetic field, and a phase-to-phase short circuit, which in most cases results in a motor / generator trip, can be easily detected with these instruments. Additionally, any anomalies of the power circuit occurring downstream of the test lead connections will be identified by a resistance imbalance.
