## Description

Powerful motor for DIY projects, automation and power tools, operates at 12-20VDC and reaches up to 21000RPM for high torque and speed. Double bearing ensures smooth running and durability, 5mm cut shaft allows secure coupling with sprockets and pulleys, 2 M4 threaded holes and rear fan help with mounting and efficient cooling.
The DC 775 motor is a robust and efficient unit, designed to deliver top performance in a variety of applications. With a supported power supply between 12VDC and 21VDC and an impressive speed of 21000RPM, this motor provides the power and speed needed for demanding tasks.
Equipped with a double bearing, the motor ensures smooth and prolonged operation, minimizing wear and maintenance.
Its 5mm shaft features a cut to allow for easy integration and reliable connection with various components or transmissions.
The motor has two mounting holes on the shaft side, with M4 thread.
For optimal engine cooling, the rear part integrates a fan that allows efficient heat dissipation. However, be careful of possible dust deposits.
IMPORTANT! The motor CANNOT SUPPORT OVER 21,000RPM! In idle, the motor reaches 21,000RPM at 20VDC. Above 21,000 revolutions per minute, the motor will not support the centrifugal force and will be damaged. DO NOT HANDLE THE MOTOR DURING OPERATION! In working mode, the motor must be firmly fixed. Any uncontrolled movement can generate centrifugal forces that it cannot support, which can cause its failure.
