What is the difference between two phase stepping motors in series and in parallel?
It rotates at a fixed angle, 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.
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 angle"
When the winding is connected in series, it can work at higher voltage and lower current environment. When connected, it can work in low voltage and high current environment.
Therefore, two-phase motor with two phase stepper driver, four phase, eight wire motor, parallel, series, unipolar type of three kinds of connection.Parallel connection: 22 phase and four phase winding, winding resistance and inductance decrease exponentially, good acceleration performance when the motor is running high speed, load torque, motor current, but need to input two times the rated current of the heating is large, the output ability of corresponding higher requirements.When used in series, the resistance and inductance of the winding increase exponentially, the motor is stable at low speed, the noise and heat are small, the drive is not required, but the high speed moment loss is great. Therefore, the user can select the four phase and eight wire stepping motor wiring method according to the requirements.The two-phase stepping motor has only two windings on the stator, with four outlets, the whole step is 1.8 degrees, and the half step is 0.9 degrees. In the drive, as long as the two-phase winding current on-off and current direction control, you can. The four phase stepper motor has four windings on the stator, there are eight outlets, the whole step is 0.9 degrees, half step is 0.45 degrees, but the drive needs to control the four windings, the circuit is relatively complex.
