How do you give in to the motor revolution for 3 seconds
The speed you want is too low, the low speed performance of the step motor is not good, and if you go directly to the motor output, you may have a lot of vibration. It is recommended that the machine run at a low speed of 2rps, and the output shaft of the motor will be reduced by 1:6 with your load, and you will be able to get 2/6rps RPM, which is the rotation of the motor every three seconds.
What difficult. Our mountain community stepped into the motor. Not only can you control it for a second, but you can also control it by 20, 10, 9, 8... Circle. You can even control it for a year, 10 years. The principle of stepping motor is that you want it to move and you want it to stop. You can also have continuous positive and negative rotation. Accurate positioning. The error is 3 ~ 5% of each step Angle of the motor.
This is the main impulse that controls the output. A step motor is a step that moves a pulse into the Angle. For example, a 1.8 degree step motor takes 200 pulses, and the actuator needs 400 pulses in half a step. Simple is directly with microcontroller programming to control the amount of output pulse and the number of pulses output corresponding to 3 seconds for the motor turn round to go, if want to consider the fine fraction of drive is set
1, directly with microcontroller programming to control the amount of output pulse and the number of pulses output corresponding to 3 seconds for the motor turn round to go, if want to consider the fine fraction of drive is set. Step by step motor is an open loop controlling element which converts electrical pulse signal into angular displacement or line displacement. In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle, known as the "step Angle", its rotation is based on the Angle of the fixed step by step. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment.
