Single 48V - 7kVA LEV Motor and Body Controller
The IBMC is the only fully integrated motor-body control solution for 48V operated light electric vehicles (classes L1e-L6e) on the market today. It was designed specifically with e-cargo bikes, e-mopeds, e-motorcycles and small 4-wheel city cars in mind. It controls one or - thanks to its master-slave scalability - multiple motors. Both hub and central, external PMSM motors are supported. The integrated body module processes all input signals from switches, throttle and brake and controls motor, lights and the display. This unique integration significantly reduces cost, space and cable connections while increasing quality and reliability compared with traditional multi ECU solutions.
Traction inverter for 3-phase electric motors having: DC-Link: 48V (nominal), DC-Link Range: 36V - 54V, Current: 130A (rms continuous) Power: 4kVA (continuous), 7kVA (boost).
Integrates both power electronics and body control functionality in a single control unit.
Support of PMSM, asynchronous, synchronous reluctance, axial or transversal flux. Full access motor control parameters and torque mapping. 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
Up to 98% efficiency. Field Oriented Control (FOC) algorithm. Highest performance and maximum torque under all operating conditions and speeds with Full Field Weakening and Maximum Torque per Ampere (MTPA) support. High energy efficiency due to recuperative breaking option. Minimum motor harmonics and torque ripple.
A 1Mbit/s CAN 2.0 bus connects the IBMC with the display, battery management system and optionally more IBMC units in slave mode. This CAN bus also serves as interface for SW updates, system monitoring and diagnostic checks.
Communication with BMS for range estimation and battery supervision
IBMC 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:
In case the IBMC functionality meets your general requirements but your specific application needs some adaptions, please contact us for further details. 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...
