48V – 15.5kVA boost Motor Controller (MC)
The MC48V280A1 offers an integrated motor control solution for 48V operated light electric vehicles (classes L3e-L6e).
It was designed specifically with e-Mopeds, e-Motorbikes, small 4-wheel city cars, e-Vehicles (L3e-L6e) in mind. It controls one or – thanks to its master-slave scalability – multiple motors.
The motor controller module provides 3 drive modes (quick customization available) and processes all input signals from CAN communication line. Vehicle body control is available as an option for a complete and integrated solution (ref. IBMC48V280A1 controller).
The MC48V280A1 controller is offered in a standard version for LEVs with integrated “On Board Diagnostic” (OBD-2) support.
Traction inverter for 3-phase electric motors having: DC-Link: 48V (nominal), DC-Link Range: 36V – 54V, Current: 115A (rms continuous), 280A (rms boost for 10s), Power: 6.3kVA (continuous), 15.5kVA (boost); Power density: 10kVA/liter; Specific Power: 9kVA/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, 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
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.
- Master/slave configuration for multiple motor drive.
- Diagnostic and safety functions.
- System protection against over-voltage, over-current, over-temperature.
- Controlled derating in case of system protection.
- Battery supervision.
A CAN 2.0 bus up to 1Mbit/s connects the MC to VMU, BMS and optionally more MC 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 according to OBD-2 standard.
MC48V280A1 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: 780g
- Dimensions (LxWxH): 152x142x44mm
- Grade: IP67
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.
