Since the rise time of IGBTs are in the range of a few tens of nanoseconds (between 50ns-200ns), even short cables between PWM motor drives and motors cause voltage doubling at the motor terminals due to Travelling Wave Phenomenon as in transmission lines. The insulation of motor windings are prone to failure due to high voltage spikes if necessary precautions are not sufficiently taken. RC Type Output Filter Modules reduce these high voltage spikes to protect motors by connecting to stator terminals.

Qualitrol
The Iris Power MDSP3 uses the Current Signature Analysis technology which relies on the concept that faults in the induction motor rotor or driven components result in changes to the rotor magnetic field pattern. Unique magnetic rotating fields are produced due to the faults which induce detectable stator current components indicative of the fault.

4535 -
Astro Flight Inc.
The purpose of the development of the 4535 was to deliver the same quality and reliability of our 32XX motors but at nearly 4x the power. Starting at the core of the motor, the 4535 uses the highest grade of sintered samarium-cobalt magnet. Unlike hobby grade neodymium magnets, these samarium-cobalt magnets are able to withstand high operating temperatures without losing magnetic strength or experiencing permanent demagnetization. Ultra-thin laminations are used in the stator to ensure minimal iron losses and maximize efficiency. All components of the motor are rated to at least 200°C to handle high continuous and burst power. Finally, to ensure manufacturing quality, all 4535 motors are designed and manufactured in Astro Flight's facility in Irvine, CA.

RMO-M Series -
IBEKO Power AB
The motor/generator winding resistance test is used to identify open windings, shorts between two windings, short to grounds, connection mistakes or shorted turns. This non-invasive test of winding resistance helps to pinpoint problems regarding windings in stator or rotor part of an electrical machine. Additionally, motor winding ohmmeter has the capability of performing heat run test which will show a change in windings resistance with an increase of temperature.The RMO-M series is designed as an ideal aid in preventive maintenance of electrical motors and generators. They are powerful (up to 100A of test current), portable (8 kg) and generate DC current which is completely ripple-free. This makes measurement very precise with 0,1% accuracy.Three voltage channels make measurement very easy since it is possible to obtain a value of all three winding resistances in one measurement

PDIV 500-T -
Shanghai Dean Electrical Co., Ltd
Differing from partial discharge with high frequency pulse which produce sound and light phenomenon, the power frequency AC voltage reaches a certain threshold, can only produce instantaneous current leakage around the tested sample, it can be detected through discharge capacity (unit: PC) to evaluate partial discharge phenomena..The instrument PDIV 500-T is designed to put samples such as enameled wire, insulation paper/film, and electric motor stator in the High temperature / humidity environment chamber, applying a power frequency voltage with a programed rising speed, and prefect ground connection must be guaranteed , through the coupling capacitor as the medium, the continuous detection of discharge capacity against the voltages will create formulation between the Voltages and discharge capacities (pc), the software will find the discharge voltage threshold called PDIV.
