Motor Control

Electric and hybrid vehicle motor converter

Production of electric and hybrid vehicles is increasing. Both have power motors (50kW or more) and use 3 to 6 phase inverters to drive the traction and generator motors precisely and reliably. The trend is to opt for high frequency and smooth wave forms, which is fuelling demand for fast current sensors. There are two distinct market needs:

• For standard products such as HC6 and HAH1DR family
• For a full custom solution which fits with the mechatronic approach

If you would like further information regarding electric hybrid vehicle motor converters, please do not hesitate to contact our technical staff, who will be happy to advise you about LEM’s standard and custom solutions in this field.

Other motor inverters

There is a huge volume of various motors that require current sensing. Typical applications include power steering, brake by wire, active suspension and electric compressors with currents that can vary from 20A up to 200A. LEM provides a whole range of products to cover these applications within the HC2 family. We are currently working on innovative standard and custom solutions that are due to be launched in the coming months.
