716 3.7V Micro Coreless Motor

716 3.7V Micro Coreless Motor is a high-speed, lightweight propulsion solution specifically designed for micro-drones, small-scale robotics, and portable handheld devices. This cylindrical permanent magnet motor utilizes a coreless design, which significantly reduces the rotor’s inertia to provide lightning-fast acceleration and highly responsive control. Consequently, this motor excels in applications where precise maneuvering and high power-to-weight ratios are critical. Operating efficiently at a nominal 3.7V, it integrates perfectly with single-cell Lithium-Polymer (LiPo) batteries. Furthermore, its compact 7mm diameter makes it an ideal choice for space-constrained electronics. Therefore, you should consider the 716 coreless motor for any project that requires reliable high-RPM performance in a miniature form factor.

Key Features:

• High Power-to-Weight Ratio: Delivering exceptional rotational speeds while maintaining a featherweight profile, this motor ensures maximum lift for micro aerial vehicles.
• Coreless Technology: The absence of an iron core eliminates “cogging” torque and reduces rotational mass, allowing for smoother operation and faster start-up times.
• Low Noise and Vibration: Precise internal balancing minimizes acoustic noise and mechanical vibration, which enhances the stability of flight controllers and sensors.
• Energy Efficient: Optimized for 3.7V operation, the motor maximizes battery life in portable, battery-powered devices.
• Flexible Installation: Pre-installed color-coded lead wires simplify the installation process into various airframes or custom enclosures.
