Product Description

The RS-775 Regular Motor features a high-grade pure copper winding and a strong magnetic field to ensure consistent performance under load. One of its standout mechanical features is the integrated cooling fan, which pulls air through the motor housing to prevent overheating during continuous operation. The front of the motor is equipped with a ball bearing, significantly reducing friction and noise while increasing the overall lifespan of the shaft assembly compared to sleeve-bearing alternatives.

Key Features

High Torque Output: Provides substantial rotational force, making it suitable for driving gears, pulleys, and heavy-duty fans.
Built-in Cooling: The internal fan ensures the motor stays within safe operating temperatures during extended use.
Durable Build: Features a rugged metal casing designed to withstand the vibrations of power tools and mobile robots.
Universal Mounting: Includes standard M4 mounting holes on the front face, compatible with a wide range of 775-series motor brackets.
High-Speed Versatility: Capable of reaching high RPMs, perfect for applications like circular saws or high-speed blowers.

Technical Details

Commutation: Brushed motor design for simple speed control using PWM (Pulse Width Modulation).
Efficiency: Optimized for a balance between power consumption and mechanical output.
Shaft Style: 5mm output shaft provides compatibility with standard 775-series gears and couplers.

Prototyping and Engineering Tips from Robogears

Current Requirements: The RS-775 is a power-hungry motor. At 12V, the stall current can exceed 10A-20A depending on the specific load. Ensure your power supply (LiPo battery or SMPS) and motor driver (like the IBT-2 or a heavy-duty relay) can handle high current spikes to prevent component failure.
Speed Control: For precise movement, use a PWM DC Motor Speed Controller. This allows you to dial in the exact RPM needed without losing significant torque at lower speeds.
Mounting Stability: Because of its high torque and RPM, this motor can produce significant vibration. Always use a heavy-duty 775 motor bracket and ensure it is bolted securely to a rigid chassis to prevent mechanical misalignment.
Flyback Protection: When using this motor with a microcontroller like an Arduino, always use a flyback diode across the motor terminals to protect your electronics from the inductive voltage spikes generated when the motor stops.

Package Includes

1 x RS-775 12V DC Motor (Regular)

Disclaimer

This motor is capable of high-speed rotation and high torque. Use extreme caution when testing with propellers or blades. Always wear safety goggles and keep loose clothing away from the spinning shaft.
