Traction Inverter

It Simply Performs Better.

EmCon Traction Inverter. Compact and Intelligent.

Traction Coonverter

The traction inverter has the task to convert supplied energy as efficiently as possible and make it available to the drive motors in a suitable way. The conversion of energy (for example from direct current into three-phase alternating current with the corresponding dynamic behaviour) is made possible by state-of-the-art power electronics.

Power and Efficiency

Using modern power electronics and highly dynamic motor control techniques, the traction inverter provides the energy for optimal tractive effort. Regardless of the operating conditions. During braking, a large amount of the braking energy is automatically fed back into the grid.

Quality and service

Whether -40°C in the snow or over +40°C in a sandstorm: Our traction inverters require minimal maintenance, are durable and extremely reliable. The well-thought-out 3-level service concept is tailored to the other drive components in the vehicle. This means high availability and low maintenance costs. With short response times and original Voith replacement parts, our service department ensures problem-free operation.
