When reliability, compact dimensions, and superior driving capability are essential for precision projects or equipment maintenance, the Mabuchi RF-370CB-11670 micro DC motor emerges as an exceptional engineering solution.
Manufactured by Japan's Mabuchi Motor Company, the RF-370CB-11670 represents a high-performance permanent magnet brushed DC motor. Its sophisticated design accommodates an impressive voltage range from 12V to 24V while maintaining operational stability. This voltage versatility enables adaptation to diverse power requirements across multiple applications.
The motor delivers variable rotational speeds corresponding to input voltage: approximately 3,000 RPM at 12V, 4,500 RPM at 18V, and reaching 6,000 RPM at its maximum rated voltage of 24V. This adjustable speed characteristic provides users with precise control over operational parameters, effectively meeting various performance demands.
The output shaft design demonstrates particular engineering excellence. Featuring a 2mm diameter shaft with combined knurled and splined geometry extending 15mm in length, this configuration significantly enhances grip strength and connection stability with transmission components like gears and pulleys.
The integrated knurled/splined design facilitates secure press-fitting connections, preventing slippage or loosening due to vibration or load variations—a critical feature for precision transmission applications. With compact dimensions of 24.4mm diameter and 30.8mm length, the motor easily integrates into space-constrained devices, making it ideal for miniaturized and lightweight designs.
Originally designed for automotive electronics, this Mabuchi motor has proven its durability in power window actuator systems. Beyond automotive uses, the RF-370CB-11670 serves diverse applications including small appliances, automation equipment, robotic joints, scale models, and industrial control systems requiring precise motion control.
The motor incorporates precious metal brushes that ensure optimal electrical conductivity and extended service life while minimizing maintenance requirements. Certain models feature explosion-proof construction, providing additional safety in environments with potential flammable gas hazards and further expanding its operational scope.
Representing Mabuchi Motor's manufacturing excellence, the RF-370CB-11670 combines stable performance, voltage adaptability, optimized shaft design, and broad application potential. For projects demanding compact dimensions, reliable power output, and precise speed control, this micro DC motor presents a compelling technical solution.
