Inverter

VECTOPOWER inverter

The compact VECTOPOWER inverter offers a fast and precise speed and torque control of the VECTOPOWER three-phase motors. The highly dynamic FPGA-based control manages the operation of asynchronous motors and PM synchronous motors. It also guarantees a stable control of the VECTOPOWER electric motors up into the strong field weakening operation.

The VECTOPOWER inverter precisely implements instructions from a central control via CAN as the required rotational speed or the required torque.

Features and functions

  • Temperature control of motor and inverter
  • The VP encoder also evaluates the absolute position even at standstill.
  • High power density (saves space in the vehicle)
  • Specially developed for use in electrical mobility applications, e.g. electric cars

Advantages

  • High power density
  • Effective safety concept
  • Design suitable for automobiles
  • Scalable characteristics

Operation modes

  • Torque pre-set via CAN, then feedback of actual speed, actual torque and the re-serve torque
  • Speed pre-set via CAN, then feedback of actual torque and the actual speed.

Interface

Data required for the process is returned via CAN bus.

Cyclically transmitted data

  • Actual torque
  • Actual speed
  • Torque still available
  • Temperatures
  • Digital / analogue inputs
  • Warnings / error messages
  • Etc.

Event-triggered data

  • All data available in the device, e.g. from internal control circuits, for diagnostics or higher-level rules
