What is the tooth spacing Angle in the step motor? What does it have to do with the step Angle?
There's not a lot of relationship, just like stepping into a motor step Angle, you're using a step motor, a step 1.8 degree Angle, and you don't have anything to do with it. Mechanical things can only calculate data, not too much. The mixture is typically 50 teeth, 1.8 degrees in rotor 4, 1.2 in 6, and 0.72 in 10.
The Angle of tooth spacing and the Angle of step distance are a concept, which is the Angle of rotation of an electric motor for each pulse signal sent by the control system. When stepping drive receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle (called "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. The step motor is an open loop controlling element which converts the 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.
According to the rotor of the 4 consecutive stagger, the Angle of the stepper motor and stator for stepper motor step Angle, through calculation 7.2/4 = 1.8 degrees, or understand it, a week with 50 teeth on the rotor, because location is different form the tooth Angle has 4 x50 = 200, 360/200 = 1.8 degrees
According to the two phases of the broken mountain club SS1404A20A, the stator teeth are 48, the rotor is divided into four sections, the upper blue is 50 teeth, the lower end blue is wrong with the upper end, and it is also 50 teeth. Top yellow 50 teeth, lower end yellow and upper end, also 50 teeth. According to known data, the rotor tooth is 7.2 degrees and the stator is 7.5 degrees.
