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.

Dynapar
Resolvers are electromechanical devices that convert mechanical motion into an electronic signal. Being analog devices, resolvers have no onboard electronics making them ideal for high shock, vibration and other harsh environments. Harowe offers frameless resolvers also known as servo resolvers or pancake resolvers consisting of a rotor assembly that is shaft mounted and a stator assembly that is mounted to the customer's device or housing as well as shafted housed resolvers with flange, servo groves and c-face mounts.

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.

Signals & Systems India Private Limited
The Display used to monitor the 20Hz and 50Hz current passing through NGT transformer. This could help to monitor the stator earth fault and could record the current every minute. The current shall be displayed in milliamps for both 20Hz and 50Hz. If an earth fault occurs in the generator star point, the 20 Hz voltage drives a current through the fault resistance. The current can be measured using clamp-on CT which would be clamped between load resistor and NGT. It gives an indication of the current values are lower or higher than the set threshold.

AWX-05S -
ECG KOKUSAI Co., Ltd.
This equipment is a system which does several electric characteristic tests, such as Armature and Stator coils. It is a system which performs an automatic test and judge according to the set-up parameters, and anyone can perform quality test judgment easily by desorbing a work. Moreover, an impulse test is efficient and does the electric examination of the winding state by not destroying the item.It is inductance and Q which the damped oscillatory wave form generated in a transient phenomenon waveform, i.e., coil, and when there are number of turns difference in a coil, a core, the difference in the material, etc. can judge it simultaneously.That is, almost all characters required as a quality of winding can be inspected very much in a short time.

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

WB Series -
Magtrol Inc.
Eddy-Current Brake Dynamometers (WB Series) are ideal for applications requiring high speeds and also when operating in the middle to high power range. Eddy-Current Brakes provide increasing torque as the speed increases, reaching peak torque at rated speed. The dynamometers have low inertia as a result of small rotor diameter. Brake cooling is provided by a water circulation system, which passes inside the stator to dissipate heat generated by the braking power. The water cooling in the WB provides high continuous power ratings (max. 140 kW). The WB dynamometers have accuracy ratings of 0.3% to 0.5% full scale ( 2% for WB 2.7), depending on size and system configuration. Additional options include: high-speed version, speed pickup, mechanical rotor blocking device, OEM version IS and vertical mounting.
