GPROPULSION / PRODUCT & R&D PORTFOLIO

Engineered around
the application.

Motor controllers, traction machines, and battery management architectures for platforms where standard hardware does not fit the duty cycle.

01 / MOTOR CONTROLLERS

Control across
voltage classes.

Every controller platform is designed and developed by GPropulsion. Low- and medium-voltage models use the VESC® ecosystem; enterprise inverter programs use application-specific architectures.

02 YEARS / CONTROLLER WARRANTYEvery supplied GPropulsion controller carries a two-year warranty. Custom design and development are available for OEM requirements.

SECOND MOTOR PROGRAM

A second custom traction motor is also in active R&D/production development. Configuration and performance data are available through an engineering discussion.

03 / BATTERY MANAGEMENT

High-C discharge.
Safety by design.

Our automotive-grade BMS architectures are in active research and development for heavy EV applications. The focus is reliable sensing, protection, and system-level behavior under sustained high-current demand.
