High Voltage e-Motors (180 kW i 36High Voltage Performance e-Motor controllers

A dual controller is used for torque vectoring two e-motors installed on one axle and an inverter for one e-motor in an affordable version.

E-Motor controller — application

The e-Motor controller will be a perfect solution for:

  • two-wheel drive vehicles;
  • four-wheel drive vehicles;
  • public heavy vehicles: buses, road sweepers, trucks;
  • construction, mining, military industries;
  • motorsports;
  • yachting;
  • retrofitting.

E-Motor controller – functionalities

The e-Motor controller manages one e-motor or two e-motors. Our controller stands out mainly by:

  • 2x CANBUS redundant communication;
  • CAN2 for a vehicle control body unit and BMS;
  • CAN3 for secure communication between axles;
  • redundant DSPs for each inverter;
  • SIMULINK programming environment for traction control algorithm;
  • preparation for ASIL-D safety certification on the final vehicle;
  • resolver, encoder and inlet temperature sensors;
  • ready-to-use ECUMASTER PMU/ADU/GPS/IMU integration;
  • Torque Vectoring application in 4WD and 2WD vehicles;
  • a DSP for motor and traction control for each motor.

Elimen’s range includes e-motor controllers in several variants. Currently we provide the following models:

  • 2x180kW INV2181-503A400V — a dual controller for torque vectoring;
  • 1x180kW INV1181-503A400V — a single controller;
  • 2x360kW INV2361-560A800V — a dual controller for torque vectoring;
  • 1x360kW INV1361-560A800V — a single controller.
