SDx
Synchros and Resolvers are transformer-type voltage/current transducers that convert a shaft or other rotating device's angular position and/or velocity to a multi-wire AC electrical signal. Both deliver signals proportional to the Sine and/or Cosine of the shaft angle. A Resolver-to-Digital or a Synchro-to-Digital converter is used to convert these signals to a digital output corresponding to the shaft angle and/or velocity.

Real Car Transient Test System
RealCar Simulation Bench
This system is suitable for transient test of actual vehicle in combination with the real-time model calculation by the measurement/control panel and low inertial motor. By replacing the wheel of the actual vehicle with the tire type bearing, the axle shaft is taken out to the outside of the vehicle and connected to the low inertia motor. It can be reproduced the sliding motion which the chassis dynamometer cannot be realized. Also, since the longitudinal force is not occurred in the vehicle, the vehicle restraint can be simplified and the behavior such as shift shock can be reproduced on the bench.

Rotation Field Testers
PeakTech Prüf- und Messtechnik GmbH
Direction indicators are indispensable for use in the electrical assembly of three-phase motors. In normal use, the test leads are connected to the live terminals, with an R / L display showing the later direction of rotation of the electric motor. In addition, this model can be used for the contactless determination of the direction of rotation of switched-off or not connected motors. Place the switched-on measuring device on the motor parallel to the longitudinal axis without test leads. Now turn the shaft of the motor, the measuring device now shows a right or left movement.

Signal Analysis
Synchronous Accumulation (Order Analysis)
Order analysis is one of the most convenient and efficient methods for diagnostics and balancing of rotating mechanisms and transmission gears. With an RPM sensor and a vibration sensor, it is possible to study the time characteristics of gear vibration signals. It is a well-known fact that a signal from a vibration sensor is affected by signals from other sources. To tune out from the disturbing signals, the synchronous signal accumulation method is used. For each shaft rotation, the RPM sensor provides a rotation mark. This signal serves as a triggering strobe for the vibration sensor signal sweeping. The obtained signal sweeps are combined. All the sources of the signals related to the shaft frequency (frequency of rotation) are accumulated and increased in the accumulator linearly proportionally to the N number of rotations. All other signals that are not correlated with the shaft frequency are accumulated proportionally to N1/2 and in case of a greater number of averagings, the useful signal exceeds the interference level.

Tachometers/Torque Meters
Tachometers measure rotational or linear speed and come in two styles: contact and non-contact. Contact models come with various rubber/plastic adapters for interfacing the instrument’s shaft with the surface of the spinning or moving surface under test. Non-contact models come with reflective tape that is placed on the surface to become the target of the instrument’s low-power laser.
