RESEARCH AND DEVELOPMENT

Hardware, firmware and motor design, under one roof.

Our R&D centre in Kochi designs the power electronics, writes the control software and validates the result, all in-house.

patents granted

controller series, 20 variants

~97%

controller efficiency, up to

ASIL A/B

compliant hardware

CAPABILITIES

Six disciplines, one team.

Because the same team owns every layer, a change in the motor, the inverter or the firmware is made with the other two in view.

Power electronics

Inverter and power-stage design for every series we make.

Power stages from 48 to 96 V, up to 16 kW peak
Up to ~97% controller efficiency
Sealed IP67 designs, rated for heat, dust and vibration

Motor control

Control algorithms written and tuned in-house.

Field-oriented control and torque control
Adaptive regenerative braking
Optimised for Indian drive cycles

Vehicle control and embedded software

Motor control and vehicle control share one unit, on firmware we own.

Integrated motor controller and VCU
CAN and UDS diagnostics
Over-the-air updates through the connected cluster

Functional safety

Safety is designed into the hardware and the logic.

ASIL A and ASIL B compliant hardware
Patented fault-detection logic
Limp-home capability

Motor design

We design the motor and its controller as one system.

Rare-earth-free EESM powertrain in development
Validated together for light commercial vehicles
Supported by an ARAI technology grant

Validation and testing

Every design is verified against a plan agreed with the customer.

Design verification plans and reports (DVP&R)
Thermal, load and endurance testing
End-of-line test development

LAB AND DESIGN TOOLS

Designed in software, proven on the bench.

Two dynamometer benches

A 5 kW and a 20 kW dynamometer bench in our lab. Motors and controllers are measured under load before a drive goes to a vehicle.

Simulation

Designs are modelled and simulated before hardware is built.

PCB design

Controller boards are laid out in-house with professional PCB design software.

Motor design software

Motor geometry and electromagnetic performance are designed and analysed with dedicated motor-design tools.

INTELLECTUAL PROPERTY

Full-stack IP, developed in India.

Hardware, firmware, and the vehicle and motor control algorithms are our own.

2021First patent granted, for a motor controller.
2026First motor patent granted.

TOOLS AND PROCESS

How the work reaches your vehicle.

Five gated phasesEvery programme follows APQP, from requirement to stable production, with a design verification plan agreed with you.See how we develop Controller SuiteOur PC tool for parameter configuration, auto-tuning, firmware update and live CAN monitoring.See Controller Suite Vehicle simulatorDrive a vehicle through the Indian Driving Cycle, inject a fault and send an over-the-air update.Try the simulator

Need something outside the standard range?

We take on custom development, including drives for industrial, marine and agricultural equipment.
