10 PCS Dual Long Shaft 775 DC Motor

The 775 Dual shaft motor delivers reliable power for a wide range of applications. Operating at 24V with a no-load speed of 3000RPM, this brushed motor features a pure copper coil, ball bearings, and a built-in cooling fan for efficient heat dissipation. Use it to replace damaged AC fan motors or power air conditioners, vacuum cleaners, electric screwdrivers, juicers, and more.

Ball Bearings for Smooth Operation

• Unlike sleeve bearings that wear and develop play over time, the 755 uses ball bearings on the shaft:
• Lower friction than sleeve bearings
• Consistent performance over thousands of hours
• Handles radial and axial loads better
• Quieter operation, especially at higher speeds

Low Current, Low Noise

At no-load, the 755 draws only 0.3A at 24V. Under load, current increases appropriately, but the motor remains efficient. The combination of ball bearings, balanced rotor, and quality construction results in low noise operation – important for applications like fans, juicers, and vacuum cleaners used in living spaces.

Reversible Operation (CW/CCW)

The 755 motor runs in both clockwise and counterclockwise directions. Simply reverse the polarity of the DC supply to change rotation. This makes it suitable for:

• Applications requiring bidirectional movement
• Equipment that needs reversible operation
• Prototyping where rotation direction may change

Replace Damaged AC Fan Motors

One common application for the 755 is replacing failed AC fan motors with efficient DC motors. Benefits include:

• Lower power consumption (24V DC vs AC mains)
• Variable speed control with simple PWM
• Quieter operation in many cases
• Longer lifespan with proper cooling

Dual Long Shaft Design

• Most motors have a single output shaft. The 755 features extended shafts on both ends, allowing:
• Dual outputs from one motor
• Flexible mounting options in tight spaces
• Counter-rotating mechanisms (with appropriate gearing)
• Easy integration into existing equipment
• Pure Copper Coil – The Mark of Quality

Pure copper: Higher conductivity, better heat dissipation, longer life

Aluminum (inferior)Lower efficiency, runs hotter, shorter lifespan

The 755 uses pure copper windings – the industry standard for quality motors. Copper's superior electrical conductivity means less energy lost as heat, more power delivered to the load, and reliable operation over time.

Built-in Cooling Fan

• Heat is the enemy of electric motors. The 755 includes an integrated cooling fan on the rotor that:
• Draws air through the motor during operation
• Dissipates heat from copper coils and bearings
• Allows continuous duty cycles without overheating
• Extends motor life significantly
