Engine HGLRC Specter 1002 21000KV (4 pcs)

Order the HGLRC Specter 1002 21000KV motor - the high-speed heart of your micro-drone

To create the smallest and most dynamic quadcopters, we present engine HGLRC Specter 1002 21000KV. This brushless motor is designed specifically for ultra-compact Whoop-class drones. It provides incredible acceleration and responsiveness on 1S batteries. You'll get the perfect traction for indoor racing and tight space flying. This motor is the key to your micro drone's incredible maneuverability.

Engine HGLRC Specter 1002 21000KV is an example of engineering in micro format. Its ultra-high KV value (21000) indicates its enormous rotation speed. The motor instantly responds to the slightest commands from the remote control. This allows you to perform sharp turns and difficult tricks. The small size and weight are ideal for maintaining the overall balance of the device. Your Whoop drone will be the fastest and most responsive in the room.

Five main advantages of the device

• Ultra-compact size 1002 (10x2mm). Ideal for the smallest Whoop drone frames. Minimum weight and dimensions for maximum maneuverability.

• Extremely high KV value 21000. Provides maximum rotation speed on 1S power supply. Gives instant response and sharp acceleration.

• High quality components and balancing. Miniature bearings ensure smooth running. Precise balancing reduces vibration for stable flight.

• Efficient stator with copper winding. Optimized for minimal energy loss. This improves efficiency and overall engine performance.

• Robust design for long service life. Built to withstand the stress of intense micro racing. Reliable operation even after numerous flights and falls.

Operating principle and technical details

Brushless motor is the power heart of the modern micro-drone. Unlike brushed motors, it does not have brushes. This increases its reliability, efficiency and service life. The work is based on the interaction of magnetic fields. The stationary stator contains windings of thin copper wire. The rotating rotor is equipped with strong neodymium magnets.

The ESC regulator (in the AIO board) supplies current to three phases of the stator windings. This creates a rotating magnetic field. It interacts with the magnets of the rotor, causing it to rotate. HGLRC Specter 1002 21000KV responds to controller commands instantly. The KV parameter shows the dependence of revolutions on voltage. Here 21000 means 21000 revolutions per minute for each volt of supply.

Specific functionality and technical characteristics:

• Standard size: 1002 (stator diameter 10mm, height 2mm).

• Construction: External rotor (Outrunner) for compactness.

• KV parameter: 21,000 revolutions per minute per volt (RPM/V).

• Recommended voltage: 1S LiPo (3.7V nominal, 4.2V charged).

• Shaft type: Small diameter, usually 1.0mm or 1.5mm.

• Weight: Extremely small, a few grams.

• Recommended Propeller: Propellers 31-40mm for Whoop drones.

• ESC requirements: A speed controller for micro drones (usually in an AIO) that supports high KV.

• Purpose: Micro-quadcopters of the Whoop class (65mm, 75mm), Tiny Whoop racing.

This engine is the choice of pilots interested in the world of micro drones. It is ideal for building a racing Whoop for indoor competition. It would also make a great toy drone.
