Machine Test System 0.3 — MOE Lab Tender Details

Machine Test System 0.3

Equipment set for recording the characteristicsof electrical machines of the 300 Watt class,consisting of:

1.) Cradle-type three-phase asynchronous machine
2.) Control unit

Cradle-type three-phase asynchronousmachinewith squirrel-cage rotor and integrated torquepick-up and integrated incremental tacho. This specially-designed machine is equippedwith sufficient power and torque reserves to
brake up to standstill or drive any of the machines contained in the electrical machinesystem, power class 0.3 kW. Torque measurement is performed using strain gaugesmounted on a very durable, highly elastic stainless steel bending bar with fullyintegrated electronics. Overload protection is performed by monitoring with thermal circuitbreakers; power supply is carried out by the control unit via a permanently connected cablewith a round 7-pin connector plug. Transmission of the measured signal values isperformed using a fix D-sub 25 connection cable.

Torque: max. ± 9.9 Nm
Speed: max. ± 5,000 min-1


Control unit equipped with microcontroller andintegrated frequency converter capable ofsupplying the power and controlling the three-phase pendulum machine and displayingthe speed and torque measurement values. Connection to the PC is also displayed.The recording of the characteristics is performed point-by-point or automatically eithermanually or with the PC in all four quadrants ofthe speed/torque plane.
