Inverter for AC Motors

Smartmotion inverters provide advanced control of AC induction motors for traction or pump functions of any electrical vehicle working with speed or torque control algorithms.


Mobile Machine Management

SmartMotion is an integrated inverter which can manage multi-function and fully configurable I/O pins for any I/O functions like digital & analogue inputs and outputs, capable of driving fans, relays’ and hydraulic valves’ coils, contactors, negative brakes and many others inductive/resistive loads.

Easy tuning

TM4 TAUTM Software is a friendly PC application for inverter setup.

Users develop applications with the TM4 TAU Software:
All features are offered as standard (“one fits all” philosophy). Virtually everything can be changed with one click in an intuitive graphical tuning environment called SmartView™.

With this software, a first run for a wired vehicle can be made in minutes.
