Mini Gear Motor 120W

The Mini Gear Motor 120W is a type of gear motor used for speed control with a compact design and lightweight, making it very easy to install and move. It is widely used in food industries such as chicken and duck rotisseries, as well as in machinery systems such as face mask production machines, stretch film wrapping machines, fabric rolling machines, etc.

Overall design of the mini gear motor 120w

The mini gear motor has an exterior made of aluminum with a blue anti-corrosion and dust-resistant paint layer, offering an aesthetically pleasing look.

The rear part of the motor is equipped with a cooling fan system attached to the rotor shaft. Enclosing the fan is a cover with air intake slots, serving to protect the fan from external mechanical impacts and direct airflow along the aluminum body for continuous, circulating motor cooling.

Internal structure of the gear motor

The 120W mini gear motor belongs to the gear motor line under 1.1kW, composed of an electric motor (which can be a 1-phase electric motor or a 3-phase electric motor) combined with a gearbox.

• Electric motor part: The stator core of the machine is wound with 100% pure copper wire, ensuring absolute electrical conductivity and meeting class F insulation standards (withstanding temperatures up to 155°C). The rotor is made of high-magnetic technical steel laminations, undergoing a dynamic balancing process to eliminate vibration and noise.
• Gearbox part: Contains a transmission gear system made of wear-resistant steel and heat-treated (hardened) to increase mechanical durability. The gears are arranged to mesh with each other according to diverse gear ratios ranging from 1/3 to 1/10,000, combined with high-grade bearings and specialized lubricating grease to ensure smooth rotation, accurately converting rotational speed from the motor to the output shaft.

Classification of mini gear motor 120w

Mini gear motors include various mounting styles such as foot mount, flange mount, right-angle output shaft, hollow shaft, and solid shaft, etc.

Mini gear motor 120w inline shaft (Symbol IKR)

The IKR inline mini gear motor 120w is the most basic transmission solution applied in linear lines. The device supports coaxial connection to the load directly via a mechanical coupling.

Technical specifications:

Practical applications:

• Food processing industry: Applied in pig roasters, automatic chicken and duck skewer roasting systems that require slow and steady rotation.
• Packaging industry: Applied as the pulling system for stretch film wrapping machines and small-sized carton sealing machines.
• F&B industry: Applied to run conveyor hot pot systems in restaurants.

Mini gear motor 120w right-angle hollow shaft (Symbol RH)

The RH right-angle hollow shaft motor optimizes assembly space for machines with narrow spaces. The concave design (hollow shaft) allows users to plug the machine’s shaft directly into the gearbox to maximize savings on auxiliary parts.

Technical specifications:

Practical applications:

• Textile industry: Applied in the rotation mechanism of fabric rolling machines, textile material conveyor belts.
• Agricultural processing industry: Applied to rotate mini agricultural product drying drum systems, chestnut roasting machines.
• Medical industry: Applied to transmission conveyors in automatic medical face mask production systems.

Mini gear motor 120w right-angle solid shaft (Symbol: RA)

The RA right-angle solid shaft motor line is specially manufactured for systems requiring a 90-degree transmission direction change. The protruding solid shaft provides favorable conditions for technicians to attach roller chain sprockets or belt pulleys.

Technical specifications:

Practical applications:

• Aquatic environmental industry: Applied to rotate the paddle wheel system of oxygen aeration machines in shrimp and fish ponds.
• Chemical and cosmetic industry: Applied to attach stirring blades for mixing liquid solutions and chemicals in small tanks.
• Automated mechanical industry: Applied to run automatic rolling doors, light-load cargo lifting winch systems.

How to reverse a mini gear motor

To change the rotation direction of a 1-phase mini gear motor shaft, you need to operate directly on the wiring board of the controller. Below is the detailed technical processing procedure:

• Step 1: Evaluate the default rotation state. Proceed to power on and start the device to check. In the initial factory setting, the motor shaft will operate in a clockwise direction.
• Step 2: Disconnect power and access the controller. Completely turn off the power supply to ensure safety. Then, use a screwdriver to open the terminal block located at the back of the speed control box.
• Step 3: Identify the signal terminal cluster. Observe the symbols on the wiring board. You need to correctly identify the position of the COM (Common) wire. This is the common connection wire and must be kept fixed; absolutely do not remove or change its position.
• Step 4: Reverse the rotation direction wire position. To reverse the shaft movement, use a screwdriver to loosen the screw and remove the wire end currently located at the CW (Clockwise) position. Transfer and connect this wire to the CCW (Counter-Clockwise) terminal position, then tighten the screw to ensure electrical contact.
• Step 5: Power on and acceptance testing. Plug the power back in and turn on the controller switch. Observe the movement of the motor shaft to confirm that the device has operated stably in a counter-clockwise direction.

The mini gear motor 120w is one of the most compact and durable transmission solutions today, meeting diversity in both domestic and industrial fields. For a more intuitive view of how the device operates and installation styles, you can refer to the video summarizing practical applications on Thanh Thai Motor’s channel. In addition, watching detailed gear motor videos from different angles will provide a more intuitive perspective for each product type.
