7x16mm Coreless Motor and Quadcopter Propeller

coreless motor, is a moving dc motor without a core, characterized by low weight, small size, and high acceleration. this type of motor has a very high speed and is used in robotics, electronic projects, and the construction of small drones. these types of motors are also referred to as silent fixed motors. the rotor of coreless motors lacks a fixed core, and its rotor is a hollow winding that is typically attached to the motor shaft.

applications of Silent stationary motors:

1. robotic projects
2. small devices such as mobile phones, tablets, smart devices, etc.
3. medical devices and laboratory equipment such as small pumps
4. office equipment such as printers, blinds, card readers, etc.

specifications of the Quadcopter motor:

1. dimensions: 16.5 * 7 mm
2. output shaft: 0.8 mm
3. length of output shaft: 4.5 mm
4. length of lead: approximately 50 mm
5. voltage: 3.7 volts
6. no-load speed: 55000 rpm (the actual speed may be less or more)
7. no-load current: 100 ~ 60 ma
8. loaded speed: with a 45 mm propeller, approximately 30000 rpm and current 1000 ma
