Overview

CubeMars GL40 Motor is a compact hollow-shaft motor designed for gimbal systems, drone/air pods, and autonomous driving navigation systems. It features a larger hollow shaft, low cogging, and low energy consumption, supporting smooth control with FOC (field-oriented control) driving.

Key Features

  • GL40 hollow shaft: 8 mm
  • Large hollow shaft, low cogging: easy to insert signal and power cables
  • Lower cogging, better control: easy interaction with the driver system
  • Only 107 g
  • IP45 rating (waterproof and dustproof performance)
  • Targeted electromagnetic design for low energy consumption and lower noise during long-time operation
  • Notice: To avoid motor damage, do not use screws that are too long; refer to the drawing
