Conducting emission suppression in a power circuit for an electric motor comprises a negative temperature co-efficient resistor and capacitor connecting one of the power lines to ground. The NTC resistor is self-stabilizing so that changes in the load current are automatically compensated for.

Conducted emissions filters

A device may be configured for updating the programming of a control system of an electric rotary machine, the device having no screen. The device may include an electrical or optical connector element for connection to the control system, enabling data to be transferred between the device and the control system and a memory for containing data to be transferred into the control system and/or for loading data from the control system. The device may include a control member, with data being exchanged between the device and the control system in response to an action exerted manually on the control member.

Devices and methods for updating the programming of a system for controlling an electric rotary machine

A converter for an electric motor or transformer, the converter being comprising a connection box having passages for electrical conductors and having a semiconductor electronic module removably fixed to the connection box. The electronic module has a radiator-forming box that is open at one end, at least one electronic card at least partially embedded in a resin cast inside said radiator-forming box, and at least one connector emerging from the resin. The opening of the radiator-forming box enables it to be fitted to the connection box. The connection box has at least one window giving access to the connector(s) of the electronic module.
