Electric motors

The engine test house allows precise measurements of RPM and torque at any engine load, being the only device that directly measures engine parameters, including actual engine torque as a function of RPM.

Electric motors – testing capabilities

Mechanical parameters of electric motors which we can test:

  • torque meter No. 1:
    • maximum torque 100 Nm, 
    • maximum speed 12,000 rpm, 
    • maximum mechanical power 125.67 kW;
  • torque meter No. 2:
    • maximum torque 500 Nm, 
    • maximum speed 7,000 rpm, 
    • maximum mechanical power 366.5 kW;
  • future torque meter: 
    • maximum 1,000 Nm, 
    • maximum speed 7,000 rpm, 
    • maximum mechanical power 650 kW;
  • approximate maximum motor dimensions: a cylinder of 52 cm in length and 32 cm in diameter (it is possible to modify motor mounts and frames for larger motors).

Electrical parameters of electric motors that we can handle with our inverters:

  • Inverter No. 1:
    • rated current 200 A, 
    • peak current 400 A (60 sec.), 
    • maximum supply voltage 700 V DC;
  • Inverter No. 2: 
    • rated current 700 A, 
    • peak current 800 A (60 sec.), 
    • maximum supply voltage 450 V DC.

The stand is equipped with a battery simulator with the following main parameters:

  • simulator power supply 3×400 V AC, 
  • continuous power 80 kW, 
  • instantaneous power 120 kW (60 sec.), 
  • adjustable output voltage 24-800 V DC, 
  • rated current +/- (bi-directional) 267 A, 
  • peak current +/- (bi-directional) 400 A, 
  • the ability to quickly prototype the required energy storage capacity and conduct long-term tests with DC voltage.

Liquid cooling of motors/inverters

  • water cooler No. 1 – maximum heat capacity 5 kW;
  • water cooler No. 2 – maximum heat capacity 10 kW.

Possibility to conduct tests with the customer’s inverters:

  • the electric power of a single inverter powered directly from the DC bus in the configuration of electric motor + generator as a load must not exceed 380 kW;
  • the electric power of a single inverter supplied directly from the 3×400 V AC network with the configuration of an electric motor + generator as a load must not exceed 650 kW.
