About the Customer:
Varroc Engineering Limited is the second largest Indian auto component group, and a leading tier-1 manufacturer and supplier to Indian 2- & 3-wheeler OEMs.
The Company is focused on designing, manufacturing and supplying exterior lighting systems, plastic and polymer components, and electrical and electronics components. It also supplies precision metallic components to passenger cars, commercial vehicles, 2-wheelers, 3-wheelers, and off-highway vehicles (OHV). The Company’s segments include polymer, electrical, engine valve, forged components, and lighting. Its products include engine and engine parts, drive transmission and steering parts, suspension and braking parts, electrical parts, and other products including body and chassis.
Challenges and Solutions:
Varroc’s systems enable the mapping of performance parameters of their EV traction motors, types: (1) Hybrid Synchronous AC and Asynchronous AC Induction motors; (2) Synchronous BLDC and PMSM; and (3) ISG motors.
In addition, the systems could also (4) test the EV Traction Motor integrated with gearbox, i.e. having two O/P’s (similar to a Transaxle); and (5) are suitable for evaluating Hub Motors.
The systems were designed for evaluating multiple types and multiple manufacturers’ motors, with ranges of up to 25 kW, of up to 80 V, and max speeds of up to 15000 rpm.
The systems included Battery Simulation, with battery cycle testing (charge/discharge), battery SOC (State Of Charge) script and SOD (State Of Discharge) script, during advanced battery simulation and simple battery simulation, drive cycle testing (real-time simulation of scooter/driver, with acceleration, brake, change of vehicle states); and Battery Testing.
All advanced requested Motors Under Test are driven by their respective controller, with different types of communication protocols (CAN, LIN, A/D, FlexRay, Speedgoat, Modbus, etc.)
