7x16 mm Motor Pair with Propeller

These 7 × 16 mm coreless motors are the size used in many palm-sized and toy quadcopters, and they come as a matched pair, one spinning clockwise and one counter-clockwise, with propellers to suit. They run from a single-cell lithium battery (about 3.7 V) and are driven with PWM through a MOSFET or brushed-motor driver rather than directly from a microcontroller pin. The coreless design gives fast spin-up and light weight, which is what small drones need for stable control. Use them to build an ESP32 or Arduino micro drone, replace worn motors on a mini quadcopter, or power small fans and models.
