Overview

Lunyee 3V Micro DC Motor is a small, electric motor that runs on direct current (DC) power. It is commonly used in a variety of applications such as toys, small appliances, and electronic devices. These motors are known for their high power-to-weight ratio and ability to operate at high speeds. They also have a low voltage requirement which makes them easy to integrate into many different types of projects.

  1. wide operating powerful rare-earth magnet
  2. temperature range: -30°c to +85°c (optional: +125°c)
  3. no cogging torque, highly dynamic performance, presice speed control
  4. low current and starting voltage extremely compact and lightweightweight
  5. design with integrated encoder all-steel housing with corrosion-resistant coating
