Machinetestsystem 1.0 KW

Machinetestsystem 1.0 KW .
Equipment set for recording the characteristics
of electrical machines of the 1000 Watt class,
consisting of:
1) Cradle-type three-phase asynchronous machine, with squirrel-cage rotor and integrated torquepick-up and integrated incremental tacho.
This specially-designed machine is equippedwith sufficient power and torque reserves tobreak up or drive any of the machines contained in the electrical machine system, power class 1.0 kW. Torque measurement is performed using strain gauges mounted on a very durable, highly elastic
stainless steel bending bar with fullyintegrated electronics. Overload protection isperformed by monitoring with thermal circuitbreakers; power supply is carried out by thecontrol unit via a permanently connected cable
with a round 7-pin connector plug. Transmission of the measured signal values isperformed using a fix D-sub 25 connection cable.
Torque: max. ± 19.9 Nm
Speed: max. ± 5,000 min-1

2) Control unit, equipped with microcontroller and integrated frequency converter capable of supplying the power and controlling the three-phase pendulum machine and displaying the speed and torque measurement values. Connection to the PC via USB. The recording of the characteristics is performed point-by-point or automatically either manually or with the PC in all four quadrants of the speed/torque plane.
