Planetary Gearbox Stepper Motors
Introduction
The reduction ratio of the planetary reducer is one of the professional terms. The reduction ratio is the main parameter value of the planetary reducer to change a certain movement. The speed, torque and inertia moment are changed by the reduction ratio of the planetary reducer. The formula for calculating the reduction ratio of the planetary reducer, the number of teeth of the ring gear divided by the number of teeth of the sun gear plus one equals the reduction ratio. The reduction ratio can be calculated according to the input speed and output speed of the reducer. The formula is the input speed divided by the output speed = The reduction ratio of the planetary reducer. The precision planetary reducer is a relatively precise machine, the purpose of using it is to reduce the speed and increase the torque. According to the number of transmission stages, it can be divided into single-stage and multi-stage reducers. A simple understanding of single-stage reducer means that the reduction ratio is small, and the two-stage reducer has a large reduction ratio. Slower, but the greater the added torque. Standard precision planetary reducer commonly used reduction ratio 1-stage speed ratio: 3, 4, 5, 7, 10. Secondary speed ratio: 15, 16, 20, 28, 30, 35, 40, 50, 70, constant speed ratio. Planetary reducer cooperates with stepper motor, servo motor and brushless motor with a certain power and a certain speed. The larger the speed ratio, the larger the torque, and the slower the output speed. The smaller the speed ratio, the smaller the output torque and the faster the output speed. The larger the reduction ratio, the relative increase in the number of transmission stages of the planetary reducer, so the efficiency of the reducer will also decrease.
Detailed explanation of the use of Planetary Gearbox Stepper Motors:
1. When the screw stepping motor works, each phase winding is not constantly energized, but is energized in turn according to a certain law.
2. The angle at which the rotor rotates with each input pulse electrical signal is called the step angle.
3. The screw stepping motor can control the angle and speed according to specific instructions. During angle control, the stator winding is changed once for each pulse input, and the output shaft rotates by an angle. The number of steps is consistent with the number of pulses, and the angular displacement of the output shaft rotation is proportional to the input pulse. During speed control, continuous pulses are sent into the winding of the stepping motor, and each phase winding continuously circulates electricity. The stepping motor rotates continuously, and its speed is proportional to the pulse frequency. Changing the power on sequence, that is, changing the rotation direction of the stator magnetic field, can control the forward or reverse rotation of the motor.
4. The screw stepping motor has self-locking ability. When the control pulse stops input and the winding controlled by the last pulse continues to be energized with DC, the motor can remain in a fixed position, that is, stop at the end position of the angular displacement controlled by the last pulse. In this way, the stepper motor can realize the rotor positioning during shutdown.
