A pack of four coreless micro motors measuring 7 × 16 mm, reaching 50,000 RPM at 3.7V. The largest in the coreless micro motor range, these deliver more torque (70 mA rated current) than the smaller variants, making them suitable for slightly heavier micro drone builds and small RC projects that need additional lift.

Key Features

  • 50,000 RPM – High-speed coreless motor at 3.7V
  • Higher Torque – 70 mA rated current for more powerful output
  • Compact Size – 7 mm diameter × 16 mm length
  • Low Voltage Operation – Runs on a single 3.7V LiPo cell
  • 0.8 mm Shaft – 5 mm shaft length, compatible with micro drone propellers
  • Pack of 4 – Enough for a complete micro quadcopter build

Specifications

  • Rated Voltage: 3.7V
  • Rated Current: 70 mA
  • Speed: 50,000 RPM
  • Motor Diameter: 7 mm
  • Motor Length: 16 mm
  • Shaft Diameter: 0.8 mm
  • Shaft Length: 5 mm

Ideal For

  • DIY micro drones and quadcopters
  • Small RC aircraft and helicopters
  • Lightweight motorised projects needing extra torque
  • Vibration motors for haptic feedback

Package Contents

  • 4× Coreless Micro Motors (7 × 16 mm)

Jargon buster

Plain-language definitions for the technical terms used above.

LiPo
A lithium polymer rechargeable battery commonly used in portable electronics projects. It matters because LiPo batteries need correct charging circuitry and care, and this board includes hardware intended for that battery type.
Torque
A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
