Third-party motor adaptation

For our customers who want to use a TM4 CO150 inverter to power and control the engine from another manufacturer, we offer to characterize the engine, if the information is not already available from the manufacturer. Our expertise  in software control guarantees the customer a reliable and rapidly available system and enables us to develop tools with much greater precision than the most frequently used methods.

Furthermore, to optimize the performance of the system in all conditions, we offer our customers the possibility of adjusting the inverter software control. Thus, the result of this system coupling  allows the engine to use the maximum possible current.
