What is the Torque of the Miniature Reduction Motor?

Micro reduction motor is a small motor commonly used in mechanical transmission system. Its main function is to reduce the speed of high speed and low torque through the reduction mechanism and convert it into low speed and high torque output. Therefore, the torque becomes a very important indicator.

Torque refers to the influence of the moment (i. e., the product of force and distance) on the rotating object, and can also be understood as the ability to rotate the object around its axis. It is usually determined by the transmission ratio of the reduction mechanism and the output power of the motor. Therefore, using different reduction mechanisms or motors, different torque outputs can be obtained to accommodate different work requirements.

Torque is very important for many mechanical transmission systems. For example, in the automatic door control system, a micro motor with sufficient torque is required to push the heavy door body; in the automatic washing machine, the motor with large torque is also needed to realize the dehydration function of clothing.

Speed refers to the time required for the motor to rotate at a certain Angle, and it is one of the most important performance indicators of the motor. The speed of miniature reduction motor is generally between hundreds of RPM to thousands of RPM. Higher speed miniature reduction motors can produce higher power, but also generate more noise and heat. Therefore, it is necessary to choose the appropriate rotation speed according to the specific needs in the application. The speed of miniature reduction motor is affected by many factors, such as voltage, current, load, etc. In general, if the load is high, the speed decreases, but the power increases. Therefore, when selecting the miniature reduction motor, it is necessary to determine the required speed and power according to the specific application. The rated speed is lower than the maximum power speed under full load. The torque of the micromotor is the force of rotation. Both the torque of the micromotor and the strength of the rotating magnetic field are proportional to the current of the rotor and are proportional to the square of the current voltage.

When energized, the current passes through the winding of the motor to create a magnetic field, and it also creates an induced electromotive force on the rotor. The interaction between these two forces creates a moment that causes the rotor to rotate. According to the ampere's law, the current is proportional to the strength of the magnetic field, so the strength of the magnetic field can be adjusted by fine-tuning the current size to control the torque size of the micromotor. In addition, the voltage also affects the torque of the micromotors. According to Ohm's law, the voltage and the current are directly proportional to each other, so appropriately increasing the voltage can increase the current, thus increasing the torque of the micromotor. So the torque of the micromotor is determined by the current and voltage factor. The speed of the miniature reduction motor is determined by the frequency of the power supply and the number of magnetic poles of the motor, and there is no direct relationship with the power. The power of the reduction motor represents the output of mechanical energy to drive the mechanical load capacity. The more the pole number of the micro reduction motor, the slower the speed will be. Under a certain power condition, the higher the speed, the lower the torque will be, while the lower the speed, the greater the torque will be.Torque is the torque output of the motor, which is usually measured in Newtonian meters (Nm). Power refers to the power output per unit of time, which is usually measured by watt (W) as a unit.

The relationship between torque and power of micro deceleration motor: torque =9550 power speed, if the speed of micro deceleration motor is 216 RPM, the power is 0.77W, and the torque is 36 through 9550 0.77 216. For the miniature deceleration motor, when the required output torque increases, the input current and power will also increase. The relationship between power and torque can be expressed by the following formula: Power = torque angular speed

The angular speed refers to the rotation speed of the motor output shaft. As can be seen from the formula, when the torque of the motor output increases, the power also increases. Therefore, there is a numerical relationship between the torque and power of micro deceleration motor.
