Geared motors Manufacturers online

Geared motors are a combination of electric motor and gearbox in one compact unit.

The gearbox reduces the speed of the motor and increases the torque at the same time. This allows the rotary movement of the motor to be efficiently adapted to the requirements of the respective application.

Below you will find an overview of the structure, function and types of geared motors, as well as an overview of the areas of application and their advantages:

Structure of geared motors:

Geared motors typically consist of the following components:

1. Electric motor: Can be a direct current motor (DC), an alternating current motor (AC) or a servomotor, depending on the application.
2. Gearbox: Mechanical component for adjusting the speed and torque.
   Types of gearboxes:
   Helical gearbox (simple design)
   Worm gearbox (high transmission ratio, self-locking)
   Planetary gearboxes (compact and efficient)
   Bevel gearbox (for angular gearboxes)
3. Output shaft: Shaft on which the rotary motion is transmitted to the load.
4. Housing: Protects the motor and gearbox from environmental influences.
5. Lubricant: For minimizing friction and cooling the gearbox elements.

How geared motors work:

The mode of operation is based on the synergetic combination of a motor and a gearbox:

1. The electric motor receives electrical energy and converts it into mechanical energy (rotary motion).
2. The rotary motion generated is transferred to the gearbox.
3. The gearbox reduces the speed and simultaneously increases the torque depending on the transmission ratio.
4. The adjusted speed and the increased torque are available at the output of the gearbox.

The most important parameters are
Speed: Speed of the output shaft.
Torque: Force acting on the output shaft.
transmission ratio: Ratio of input speed to output speed.

Types of geared motors:

Geared motors can be designed differently depending on the application and structure:

1. Helical geared motors:
   Simple design and cost-effective.
   Suitable for linear movements and moderate loads.
2. Worm geared motors:
   High transmission ratio.
   Self-locking feature prevents load backlash.
3. Planetary geared motors:
   Compact, high efficiency and load capacity.
   Often used in robotics or precision applications.
4. Bevel geared motors:
   Allow changes in direction of movement (e.g. 90 degrees).
5. Cycloidal geared motors:
   Extremely robust and suitable for high torques.

Use of geared motors:

Geared motors are used in many different areas:

1. Industrial applications:
Conveyor technology: drive of conveyor belts, escalators or elevators.
Mechanical engineering: Drive of machine tools, packaging machines or production systems.
Automation technology: Use in robots and assembly lines.

2. Transportation and logistics:
Drives in conveyor systems, cranes, forklifts and conveyor belts.

3. Vehicle technology:
Driving windows, windshield wipers or electric doors in vehicles.

4. Building technology:
Drives for roller doors, roller shutters or elevators.

5. Energy technology:
Use in wind turbines or solar tracking systems.

6. Domestic appliances:
Drive for washing machines, kitchen appliances or air conditioning systems.

Advantages of geared motors:

• A compact design thanks to the combination of motor and gearbox.
• High efficiency by adapting torque and speed to the application.
• Versatile use in almost all industrial sectors.
• A long service life is achieved through robust design and low maintenance requirements.
• Self-locking, e.g. in worm gearboxes, provides an additional safety function.

Geared motors are versatile, efficient and reliable drive solutions for numerous applications in industry, logistics and everyday technology. Their ability to adapt torque and speed to the specific requirements of a task makes them indispensable components in modern systems.

Here is an overview of the most important criteria to consider when buying geared motors:

When buying geared motors, various technical, economic and application-related criteria should be considered in order to make the optimal choice.

• Choose robust and durable models for continuous use in production machines, conveyor systems or machine tools.
• Robotics and automation systems require geared motors with low backlash and high precision (e.g. planetary gearboxes).
• For hygienic areas (food industry), geared motors made of stainless steel and with food-safe lubricant are required.
• Flange drive, foot mounting or hollow shaft mounting depending on local conditions.
• The required torque (Nm) must be known, as it determines how much force the motor can transmit to the load. Tip: Select the torque with a safety margin to compensate for unexpected loads.
• Required output speed (rpm) after the gearbox. The transmission ratio of the gearbox should be selected so that it matches the required speed.
• A high transmission ratio reduces the speed and increases the torque. The appropriate gearbox must be selected depending on the application (precise control or high speed).
• Motor power in watts (W) or kilowatts (kW), depending on the required load and duration of operation.
• Select the gearbox type to suit the application:
• Helical gearbox: Simple and efficient.
• Worm gearbox: High transmission ratio, self-locking.
• Planetary gearbox: Compact, high efficiency.
• Bevel gearbox: For angular drives (90 degrees).
• Ensure that the geared motor is designed for the intended use: Continuous operation = continuous load. Intermittent operation = short operations with breaks.
• If loads fluctuate greatly, a motor with overload protection should be selected.
• Select energy-efficient motors, especially for continuous operation. Motors of efficiency classes IE2, IE3 or IE4 reduce energy consumption.
• The space requirement of the geared motor must match the installation space.
• Note the installation position (horizontal or vertical).
• Ambient conditions such as temperature, humidity, dust or chemical exposure: e.g. IP65 for dust and splash-proof applications.
• Stainless steel housing for hygienic or corrosive environments.
• For noise-sensitive environments (e.g. office or living area), a particularly low-noise geared motor should be selected.
• Check the availability of certifications such as ISO 9001.
• Look for information on the service life of the bearings, gears and seals.
• Geared motors with high-quality lubricants and components have longer maintenance intervals.
• Geared motors should be easy to maintain (e.g. simple lubricant change). Tip: Choose models with a good spare parts supply.
• Check the manufacturer's warranty conditions and customer service.
• Good after-sales service is crucial for long-term reliability.
• Compare the total costs (purchase, operation, maintenance). A cheap motor can result in higher maintenance and energy costs in the long term.
• Energy-efficient models save operating costs during continuous use.
• Check whether the motor is immediately available or has longer delivery times.

When purchasing geared motors, it is crucial to consider both the technical requirements and economic and operational factors. A detailed analysis of the application, operating conditions and life cycle costs will ensure that the geared motors will operate efficiently and reliably. A careful comparison of different manufacturers and models helps to make the best decision.
