L3e-L7e Motor Controller

96V – 66.5kVA boost Motor Controller (MC)

The MC96V600A1 offers a motor control solution for 96V operated light electric vehicles (classes L3e-L7e).

It was designed specifically with light electric vehicles (L3e-L7e) in mind, including e-mopeds, e-motorbikes, small 4-wheel city cars. It controls one or – thanks to its master-slave scalability – multiple motors. It is offered with integrated “On Board Diagnostic” (OBD-2) support.

The MC96V600A1 is composed by a control board designed by Ideas&Motion combined to a Semikron® SKAI3LV power module.

Motor support

Traction inverter for 3-phase electric motors having: DC-Link: 96V (nominal), DC-Link Range: 72V – 118V, Current: 200A (rms continuous), 600A (rms boost for 10s), Power: 24.0kVA (continuous), 66.5kVA (boost); Power density: 30kVA/liter; Specific Power: 12kVA/Kg. Support for multiple motor types (including PMSM, TFM, BLDC). Full access motor control parameters and torque mapping.

Flexible support of position sensors and interfaces including digital Hall sensors and encoders (optional Sin/Cos analog sensors).  Support of motor temperature sensors.

Easy motor specific adaption independently of motor manufacturer. In case you do not have access to the detailed technical motor specification, I&M offers to characterize the motor for you on our in-house test bench.

High Efficiency Power Electronics and Motor Algorithms

“Field Oriented Control“ (FOC) or “Direct Flux Vector Control” (DFVC) control alghoritms available. Highest performance and maximum torque under all operating conditions and speeds with “Full Field Weakening“ support. Up to 98% efficiency, that means increased vehicle range.

High energy efficiency due to recuperative breaking option. Minimum motor harmonics and torque ripple.

Additional functions

  • Master/slave configuration for multiple motor drive.
  • Multiple drive modes (quick customization available)
  • Diagnostic and safety functions.
  • System protection against over-voltage, over-current, over-temperature.
  • Controlled derating in case of system protection.
  • Range estimation (via BMS communication) and battery supervision.


An insulated CAN 2.0 bus up to 1Mbit/s connects the Motor Controller to auxiliary devices and optionally more MC96V600A1 units in slave mode. The communication to BMS ensures adavanced range estimation and battery supervision features. The same CAN bus also serves as interface for SW updates, system monitoring and diagnostic checks supported by UDS (Unified Diagnostic Services) protocol through ODB-2 standard.

Mechanical Design

MC96V600A1 mechanical housing has an aluminium base plate acting as a heatsink for the power electronic circuits, and shall be connected either to chassis or to an air cooler for proper functionality.

The mechanical housing has been designed to fulfil the following characteristics:

  • Weight: 2000g
  • Dimensions (LxWxH): 140x150x80mm
  • Grade: IP66

Customization Required?

In case the IBMC functionality meets your general requirements but your specific application needs some adaptions please contact us. Due to the modular design many modifications can me made quickly and with low effort. Options include e.g. changes of nominal operating voltage to 60V or 72V, adapted body features, modified motor control algorithms etc.
