RU Gear Motor is a monoblock drive mechanism that structurally combines an electric motor and a gearbox in a single housing. Previously, to achieve low speeds and high torque, a separate motor connected by a coupling to the gearbox and mounted on a common frame was used. This required additional installation work, precise shaft alignment, and took up more space. The modern gear motor solves these problems more compactly, efficiently, and reliably.
In this article, we will look at why gear motors have become the industrial standard, which five key advantages they provide, and in which industries they find wide application.
What is a Gear Motor?
Operating Principle
The electric motor produces rotational movement at high speeds, and the gearbox with its system of gears reduces the speed to the required level while increasing the torque on the output shaft. Thanks to the monolithic design, the motor shaft and gearbox shaft are perfectly coaxial, minimizing losses and vibrations.
Classification and Main Types
Cylindrical – the most common, characterized by high efficiency and uniform torque transmission.
Worm – compact, provide self-locking, but have somewhat lower efficiency.
Planetary – very compact with high torque, often used in robotics.
Bevel-Cylindrical – transmit rotation at a 90° angle, useful for complex drive configurations.
5 Main Advantages of Gear Motors
1. Compactness and Space Saving
The monoblock design of the gear motor is significantly smaller in size compared to the "motor + coupling + gearbox on a frame" system. This is especially important for:
portable devices and robotic modules;
machines with limited installation space;
conveyors and equipment for the food industry.
2. Ease and Speed of Installation
Instead of four separate units, only one is installed. There is no need for lengthy shaft alignment and coupling adjustment:
30–50% reduction in installation time;
minimum tools and installer qualifications;
quick disassembly during maintenance.
3. High Reliability and Longer Service Life
Perfect shaft alignment eliminates vibrations caused by inaccurate centering. The absence of an additional coupling reduces the number of components that can fail.
less vibration – longer bearing life;
no elements requiring regular replacement;
high resistance to overloads.
4. Higher Efficiency (Coefficient of Performance)
The optimized design reduces mechanical losses that occur when using intermediate connections:
3–5% additional energy remains in the system;
low housing heating during operation;
increased energy efficiency in long-term operation cycles.
5. Economic Efficiency
Direct and indirect cost savings:
the total cost of a gear motor is often lower than a set of motor, gearbox, coupling, and frame;
less spending on installation work and maintenance;
quick return on investment due to reduced operating costs.
Common Areas of Application
Conveyors and Transporters: belt, roller, and chain lines at factories, logistics centers, and the food industry.
Mixers and Blenders: chemical reactors, pharmaceutical mixers, food dispensers.
Machine Tool Industry: feed drives, table rotation in metal and woodworking machines.
Packaging Equipment: packing machines, labeling machines.
Agricultural Sector: feed dispensers, screw conveyors, greenhouse ventilation systems.
Lifting and Transport Equipment: winches, gates, barriers.
For example, at one food factory, the MRC series gear motor was used for a belt conveyor: thanks to its compactness, it was possible to place the drive without changing the workshop layout, and its high reliability reduced line downtime by 20%.
How to Choose the Right Gear Motor?
Motor Power (kW) – correlate with the required load.
Output Speed (rpm) or Gear Ratio – depends on the technological process.
Torque (Nm) – consider starting and maximum loads.
Gearbox Type – worm, cylindrical, planetary, or other.
Mounting Position – foot, flange, or combined.
Operating Conditions – temperature, humidity, dust formation possibility, explosive environments.
Conclusion and Call to Action
The gear motor is a modern, engineering-sound solution that provides compactness, high reliability, and cost savings. Using a monoblock drive simplifies equipment design, speeds up installation, and reduces operating costs in the long term.
