Vega

Enclosed GaN motor controller. Vega means “speed”.

A sealed single-motor speed controller for the 22-inch class, one per lift motor on Shadanga and Uddan.

Vega is a sealed single-motor electronic speed controller for the 22-inch class: a slim anodised aluminium enclosure with a ribbed heat-sink on top, battery leads at one end and three phase leads at the other. One Vega sits in each arm of Shadanga, and the same unit drives the lift motors of Uddan.

Where it fits.

Per-arm propulsion control on 6S to 14S multirotors and lift-plus-cruise VTOL aircraft.
Field-replaceable as an arm assembly: unbolt four ears, unplug three connectors.
Carries the SPATICS GaN power stage and field-oriented control firmware.

Works with.

Shadanga Hexacopter

Uddan Fixed-wing VTOL

Motors: 22-inch class outrunners on Shadanga and the lift motors on Uddan.
Flight computer: the STM32H7-class SPATICS controller over DShot with DroneCAN telemetry; ArduPilot and PX4 compatible.
Mounting: four M3 ears on a flat arm saddle, with the heat-sink in the propeller downwash.

Key features.

Sealed enclosure
Black anodised body and end caps, two recessed orange gaskets between shell and cap, and four cap screws inboard of the chamfers.
Top heat-sink
Low parallel fins with a brushed finish cover most of the deck, sized for the 14S thermal budget without a fan.
Conventional wiring
Two battery leads to a single XT60-class connector, three insulated bullet phase leads, and a signal harness with a three-position servo plug through a sealed gland.
Four flush mounting ears
Set into the base plate, so the unit sits flat on the arm.
Status LED
Beside the control-port marker, with a green control-port key and orange identification on the power side.

Specification.

Vega specification

All figures are indicative targets, subject to electrical and thermal validation; the continuous rating assumes propeller airflow over the heat-sink.

Vega is concept hardware in development and is not offered for sale. Export may be subject to Indian SCOMET controls.

Design and materials.

Near-black anodised aluminium with a brushed heat-sink, warm gold contacts, a fine moulded grain on cable boots and connectors, and black-oxide screws. The gaskets are the one orange accent.
