EM-211.01 | Determination of Gear Efficiency

  • LxWxH: 1060x600x420mm (experimental unit)
  • Weight: approx. 35kg
Technical Specification
A complete test system with drive and brake unit and two different gears. Driving and braking power are calculated to determine the efficiencies. The components used are common in drive technology and therefore closely related to practice. A three-phase AC motor with variable speed via frequency converter serves as the drive unit. An electromagnetic brake is used as the brake unit. The constant braking effect can be very finely adjusted via the exciting current, it then serves as a tunable load. The properties of the magnetic particle brake can be investigated in an additional experiment.
