Bench Testers

 
 

Bench tester are aimed for testing electric drives, motors, power generators, geared motors, air-powered and hydraulic motors, petrol engines, pneumo and hydraulic actuators with capacity from 90 W up to 60 kW for mass production or incoming inspection. All bench testers when completed go through primary appraisal by specialists from FGU Tomsky CSM.

Bench testers allow setting up and adjusting brake loads, as well as the following technical parameters of the tested devices:

  • Load torque
  • Rotation rate
  • Acceleration and deceleration time
  • Value and frequency of generated voltage and currents


Display System

The standard bench tester consists of load stand, control cabinet, automated work station.

NOTE!

  • Load stands and control cabinets can be supplied separately
  • Upon request load stands and control cabinets can be manufactured with functions and parameters required by the Client
  • Detachable adapters can be manufactured to fasten various equipment to load stands

 


 

Automated work station allows to control testing both in manual and automatic mode, visualize the set tasks and data signals from tested devices, to perform oscillographic testing of time dependencies for measured parameters and investigate them.

Standard load stand consists of the frame, loading device, torque sensor, rotary rate sensor and hydraulic and mechanical brakes.

Synchronous generator, operating for active load, is used as a loading device when testing drives and motors. It is possible to run the mode of power recuperation into feeding circuit.

The stand can be used for testing electric generators of various types.

Standard control cabinet consists of three phase voltage wiring, voltage converter into required frequency and amplitude, voltage filter network, interface units for connection with PC, high voltage generator of impulse interference, as well as required control and display devices. Control cabinet can be additionally equipped with automated workstation based on PC and required software.

 

Functions of Control Cabinet

  • Generating three phase feeding voltage within the range from minus 50 up to plus 47% out of nominal circuit voltage
  • Generating voltage losses
  • Measuring current and voltage at circuits of electric motor, drive and generator
  • Changing the feeding voltage frequency from 40 to 60 Hz
  • Changing phase sequence of output feeding voltage
  • Protection from current overloading and short circuits when loaded
  • Generating high voltage impulse interference up to 4kW
  • Automatic testing
  • Exchanging data with PC through USB interface
