What is the angle of pitch in a stepper motor and what does it have to do with the step angle?
According to the split hill SS1404A20A two-phase stepping motor, the stator teeth are 48, the rotor is divided into four segments, the upper blue 50 teeth, the lower end of the blue and the upper offset, but also the 50 teeth. The upper Yellow 50 teeth, the lower Yellow and the upper offset, but also 50 teeth. According to the known data, the rotor tooth pitch is 7.2 degrees, and the stator tooth pitch is 7.5 degrees.
The stepping motor is an open loop control element which transforms the electric pulse signal into angular displacement or linear displacement. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle, called "step", it is the rotation of the fixed point of the operation step by step.
The angle of pitch and step angle is a concept that refers to the angle at which the motor rotates when each pulse is transmitted by the control system. When the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle (called "step"), it is the rotation of the fixed point of the operation step by step. Number of pulses can be controlled by controlling the angular displacement, so as to achieve the purpose of accurate positioning; at the same time by controlling the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed.
