Curtis High Voltage Motor Controller - GMI 070

High-voltage AC motor control (400 V class): Supports electrified systems up to ~100 kW.

Field-oriented control algorithms: Deliver maximum torque, smooth response, and high efficiency.

Supports AC induction and PMAC motors: Broad motor compatibility.

Dual ARM Cortex microprocessors: Enable fast control and support functional safety architectures.

Integrated Vehicle Control Language (VCL): Combines motor and vehicle-level control in one device.

Liquid-cooled aluminum housing: Optimized thermal performance for high-duty applications.

Wide operating voltage range: Compatible with modern lithium-ion battery systems.

Advanced CAN capabilities: Dual, fully isolated CAN ports with J1939 and CANopen support.

Flexible isolated I/O (8–32 V): Simplifies integration with sensors, actuators, and vehicle subsystems.

Comprehensive diagnostics and protection: HVIL, thermal protection, overvoltage handling, and fault logging.

Rugged environmental design: IP6K9K/IP67 ingress protection for harsh off-highway conditions.
