Electrical Drive systems

The Dimopeq team offers engineering services and technical support in the fields of electrical drives and power electronic systems for traction, industry and energy systems. According to your needs we prepare the specification, clarify the given system interfaces and create concepts for the implementation of the drive system.

Detailed, customer-specific models and simulations of all drive components enable the dimensioning of a reliable, safe and efficient system. Furthermore, the models are used to calculate occurring harmonics and their influence on supplying grid as well as machine’s torque pulsations and compare them with required standards.

In addition, Dimopeq engineers support your testing and commissioning phase as well as product documentation. All our detailed services in the field of electrical drive systems can be found here:
