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.
