For hybrid vehicle motor - generator resolver - positioning system development and laboratory testing.

  • Simulation and Measurements Modes
  • In Simulation Mode the RS02 accepts the external resolver excitation voltage and generates the sine and cosine output voltages to simulate rotation at given speed or stop position at a given angle, it also simulates a preprogrammed transformation ratio. In this mode two sets of additional outputs are available. For standard encoder A, B, Z and for three phase position sensor U, V and W
  • In Measurement Mode the RS02 has 3 differential voltage inputs. It measures the sine, cosine, excitation voltages and the excitation frequency. The value of the transformation ratio is calculated. Angular position is also measured. Operates with external or internal excitation sources. The voltage and frequency of the internal excitation source is programmable
  • Programmable operation via embedded controls, PC with USB or Ethernet connection and the MTC Program
