CubeMars GL40 II KV82.5 Motor
CubeMars GL40 II KV82.5 Motor
The GL II series motors, specifically engineered for premium gimbal systems, excel in both gimbals and autonomous driving applications. Advancing from the GL series, the GL II series incorporates a cutting-edge electromagnetic and structural design. Key enhancements include a larger hollow shaft diameter for accommodating more slip rings, optimized slot torque for improved low-speed servo performance, and a new hollow drive board for precise motor control. These upgrades deliver superior product performance and increase client satisfaction.
1. Highly Integrated (All-in-One Design)
Two-in-one structure: Compactly integrates the gimbal frameless motor with the drive control board, eliminating the need for external standalone drivers, complex wiring, and connectors.
Compact and lightweight: Reduces overall volume and weight.
2. High-Performance Core Components
High Torque Density Motor: Utilizes premium neodymium iron boron magnets and an optimized electromagnetic design in a frameless motor, delivering exceptional torque output and efficiency while maintaining a compact footprint.
Low cogging torque design: Ensures exceptionally smooth operation at low speeds through magnetic circuit and structural optimization, eliminating stuttering or jitter for compatibility with diverse gimbal systems.
3. Intelligent Drive & Control
Multiple Control Modes: Supports torque control, speed control, and position control modes, adapt to different application scenarios.
4. Advanced Communication & Interface
Support for CAN and PWM
Plug-and-Play: Provides standardized electrical and mechanical interfaces, controllable by sending commands over the bus, significantly lowering the usage threshold.
