Product Overview

The ZGC40JM Series is a 40mm Outer Rotor Brushless DC Motor specifically engineered for precision-controlled applications. Featuring a 26-pole high torque density design and IP65-rated protection, this series delivers exceptional smoothness and stability, especially at low speeds. Whether integrated into propulsion systems for industrial drones or used for high-precision camera gimbal (Pitch/Yaw) adjustments, the ZGC40JM ensures reliable and consistent power output for demanding environments.

Key Features

• Superior Smoothness with 26-Pole Design: The high pole count (14 pole pairs) significantly reduces torque ripple, ensuring silk-smooth stability for gimbal stabilization systems and crystal-clear imaging.
• Rugged Environment Adaptation (IP65): Engineered with an IP65 waterproof and dustproof rating (excluding the output end) and a wide operating temperature range of -20°C to 60°C, it is built to excel in harsh outdoor missions.
• High Efficiency & Low Heat: Optimized with low line resistance (as low as 0.81Ω) and low inductance, this High Efficiency BLDC Motor maximizes battery life and minimizes thermal buildup during extended operations.
• Compact & Lightweight (145g): At only 145g, the lightweight form factor provides an excellent power-to-weight ratio, minimizing the overall payload for UAVs and handheld devices.
• Flexible Control Modes (Open/Closed Loop): Integrated with high-reliability Hall sensors for precise position feedback and commutation. It supports both cost-effective Open-loop operation and High-precision Closed-loop control, catering to diverse needs from robotic mowers to industrial inspection gimbals.
• Versatile Performance Specifications:

1. 12V Version: Optimized for High Torque (0.11 N.m) and low-speed stability—ideal for precision industrial inspection and handheld gimbal Pitch/Yaw axes.
2. 24V Version: Optimized for High Speed (4400 RPM)—perfectly suited for drone propulsion systems or fast-response brushless garden tools.

Performance Data

One-Stop Power Solution: ZGC Original Driver Integration

To unlock the peak performance of the ZGC40JM series, we recommend pairing it with ZGC’s self-developed Brushless Motor Drivers. Our official drivers feature advanced algorithms specifically tuned for the 26-pole configuration, providing superior commutation logic and current control. This hardware-software synergy ensures rapid dynamic response in closed-loop modes while effectively suppressing vibrations at low speeds for an ultra-smooth control experience.
