How to choose the gear reducer motors rightly?

In the reducer product series, gear reducer motor because of its small size, high transmission efficiency, wide selection of deceleration range, high precision, is widely used in servo, stepping, dc and other transmission systems. Their function is to ensure precision transmission premise, mainly used to reduce the speed and load/motor rotation to reduce the inertia ratio.

How to select a Gear Reducer Motor?

1. When choosing a gear reducer, it should be noted that:
Multiply the rated torque of your selected servo motor by the reduction ratio, and the value obtained is in principle less than the rated output torque of similar reducer provided by the product sample.
Also consider the drive motor, actual overload capacity and maximum operating torque, the maximum operating torque required is less than 2 times the rated output torque.
After the above conditions are met, please select the minimum reducer. Smaller reducers cost less. If there is not enough space for the motor reducer to connect in a straight line, you can also choose a Right Angle Gear Shaft Motors, which can make the torque 90 degrees.

2. Return clearance of gear reducer should also be considered
The smaller the return clearance, the higher the accuracy and the higher the cost. The user should select a speed reducer that meets the accuracy requirements.

3. Lateral/radial forces and average life should also be considered.
A reducer with large transverse/radial forces is very reliable for installation and use and is not likely to cause problems. Usually its average life is much longer than the life of the servo motor.
After meeting the above criteria, you can select the gearbox suitable for your motor according to the product catalog provided by the company in terms of installation size, axle diameter and input flange.

4. Finally, you must also consider the weight of the gear reducer motor.
A speed reducer is only allowed to match a motor of less than a certain weight. The motor is too heavy, which may damage the input flange of the reducer.

Why electric motor should use speed reducer (gearbox)?

What are the advantages of using speed reducer (gearbox)?

Veer Motor manufactures helical type and worm type gear reducer (gearboxes) for gearmotor. All of our gear speed reducers have excellent quality and power transmission applications.

Speed reducer (gearbox) is the special device which used for reducing rotation speed and improving output torque. Speed reducer (gearbox) is the important part of mechanical drive system, at present, many applications with speed reducer (gearbox), such as transportation industry, construction, mechanical processing, and other yields. So, what are the benefits of speed reducer (gearbox) in using?

Speed reducer (gearbox) can effectively protect electric motor. In operation, speed reducer is borne more bigger torque than motor, while overload, which is transmitted to the motor as long as the overload is divided by the gear ratio.
Cost saving, if there assumes electric motor is borne torque directly, while the electric motor will be broken under overload, oppositely, if there is the speed reducer in front of the electric motor, just to change the speed reducer easily with less cost.
Speed reducer effectively reduces the moment of inertia, which can timely control start and stop, and speed change. On the other hand, the torque is improved by speed reducer rather than increase the input power. So, for cost of increasing power, speed reducer is cheaper than electric motor.
Effectively save energy, to use the speed reducer can meet that same output torque with less current.
With speed reducer can effectively reduce the rotation speed and increase the torque, and output the gear ratio according to electric motor.
Effectively reduce the load inertia of the motor.

Whether Speed Reducer (Gearbox) Matches Electric Motor?
The gear reduction motor has both speed index and torque index, the rotate speed and torque are different even the powers of gear reduction motor are same, so as long as the gear motor is adopted by hard connection, there should be considered two indexes (rotate speed and torque). If the torque doesn’t meet the need torque from gear motor that the motor will vibrate or not rotate. Of course, in many times, in cases of rotate speed from high to low, the speed reducer (gearbox) can still running, but there is a defect, if gear motor is running for a long time, which will overload.

Whether Gear Reduction Motor is overloaded or not?
In general situation, the gear reduction motor is used with other devices during running, the overloads are the needed, and each transmission equipment has their limit load index. So, the limit load index of gear motor should consider all members in whole, and environmental factor, etc. So, load determination is also an important factor to analyze vibration faults.

How to adjust the rotation speed of DC gear motors?

The rotation speed of DC gear motor can be adjusted by yourself. If the gear motor is not DC gear motor, which the rotation speed can be adjusted by DC supply power with adjustable voltage function. The voltage of supply power high or low will affect the rotation speed of DC gear motor.
There are different of reduction speed with adjustment speed of DC gear motor. Adjusting rotation speed, which is changing the voltage of supply power or changing the parameters of drive circuit of DC motor, then to achieve the purpose of adjusting the rotation speed. But for reduction speed (in most cases), which is installed a gearbox with some gear ratio on the end of output shaft of motor, then to reduce the rotation speed, but at the same time increase torque.
DC motor is divided into brush motor and brushless motor, the former can be adjusted by changing the voltage of supply power; the voltage of the latter supply must be constant, and the rotation speed is adjusted by driver.
There are two kinds of drivers of brushless DC motor: built-in and built-out. For built-in type, which cannot be adjusted the rotation speed, but the rotation speed of built-out type can be adjusted or not, which depends on the internal structure of drive.
Magnetic DC motor is brush motor mostly. If rated operational voltage is 12v, you can use the 0~12v of DC stabilized power supply to power, and then the motor can be adjusted speed in stepless situation.

The contrast between geared DC motor and geared AC motor

Geared DC motors can be defined as an extension of DC motor which already had its Insight details demystified. DC Motors convert electrical energy (voltage or power source) to mechanical energy (produce rotational motion). They run on direct current. The DC motor works on the principle of Lorentz force which states that when a wire carrying current is placed in a region having magnetic field, then the wire experiences a force. This Lorentz force provides a torque to the coil to rotate. A geared DC Motor has a gear assembly attached to the motor. The speed of motor is counted in terms of rotations of the shaft per minute and is termed as RPM. The gear assembly helps in increasing the torque and reducing the speed. Using the correct combination of gears in a gear motor, its speed can be reduced to any desirable figure. This concept where gears reduce the speed of the vehicle but increase its torque is known as gear reduction. This Insight will explore all the minor and major details that make the gear head and hence the working of geared DC motor.

What are the purposes of a gear reduction motor?

Gear Reduction Motor is a gearbox that connects devices or drive machines. The main transmission structure is integrated and assembled by drive motor, shaft, and gearbox, which has the functions of connecting, transmission, deceleration, increase torque, and etc.
Principle of deceleration of gear reduction motor is to achieve the purpose of deceleration, which driving power of high-speed is from driving source to pass the power to output shaft of reducer by input shaft. Because the number of teeth of motor is more than gearbox, so the rotate speed is reduced, and the torque is increased. The main function of gear reduction motor is reducing the speed of motor, and increase torque by gear ratio.
