Hybrid Stepping Motor H421 (42MM) - Nema 17

Q: The step motor knows how to subdivide, how do you figure out the number of pulses required to turn a circle: The above target 200 is 200 pulses turning a circle, and so on.I hope my answer will help you。

Q: What are the advantages and disadvantages of stepping into the motor?: The disadvantages of stepping into a motor are as follows: If the control is not easy to generate resonance; It is difficult to operate at a high speed. It's difficult to get a big torque There is no advantage in volume weight, low energy utilization. More than the load, the synchronization will be broken, and vibrations and noise will be emitted at high speed.

Q: It's not enough to step into the motor: In the case of actuators and motors, increase the adjustment of the actuator. Or increase the power supply voltage of the actuator. Or a large motor or drive.

Q: What happens when the step motor lock stops and stops?: Do you mean the motor shaft is locked when the motor stops? Disconnect the power supply? The step motor is like this, he has stopped the current, he assures the stepping motor to locate, and when the power supply is cut off, the current is not stopped.

Q: How to control the step motor with s7-200, how to control the yield to the motor, how to stop?: Use the continuous pulse output command (speed control instruction) from the s7-200. Stop also using the instructions, detailed in your instruction manual for Siemens.

Q: What is the difference between the two phase step motor series and the parallel: So the two-phase motor has two phase step actuation, and the four phase eight wire motor has parallel, series, unipolar three kinds of connection. And connection method: four two two phase and phase winding, the winding resistance and inductance exponentially decreases, and when the motor running speed performance is good, high speed with load torque, but the motor need two times the rated current input current, fever is larger, the driver output capacity requirements increase. In series, the winding resistance and inductance increases exponentially, motor stability during low speed running, less noise and fever, to drive demand is not high, but high-speed torque loss is big. So the user can choose the four-phase eight line step motor connection method according to the requirement. Two phase stepper motor only two on the stator winding, has four stages, the step is 1.8 °, half step is 0.9 °. In the drive, it is possible to control the circuit and current direction of the two phase winding. And four phase step motor with four windings on the stator, eight root, the step is 0.9 °, half step 0.45 °, but need to control four windings of the drive, the circuit is relatively complex.

Q: How does the step motor achieve position control: In the control of the step motor, it can be more accurate if handled well. Typically, a step loss occurs when the load is strong, but it can be overcome in certain circumstances: First, it must be enough to choose the step motor power, which is enough torque. 2, the matching of subdivision and rotational speed must be taken into account. 3, the current of the power supply should be sufficient, the current adjustment of the step motor should be more suitable, as far as possible, put in the larger position. Using a controller with a reduced speed control, this can effectively overcome the loss of inertia caused by inertia.

Q: How to determine which is the phase A and B of the two phase four step motors?: In fact A, B is relative. If the motor is flipped, just swap the two.

Q: The difference between dc brushless motor and step-motor: The difference between a dc brushless motor and a stepper motor is: 1) dc brushless motor is faster than stepper motor. Dc brushless motor is controlled by the hold-element location. Stepper motor is driven by single pulse voltage directly, don't need a hall element, can be added to the motor by controlling the number of pulses to precise positioning rotation Angle. 3) the principle of driver is different, so the general dc brushless motor is used to control the low precision. The step motor is used to control the higher precision.

Q: What are the advantages of step-motor versus private motor?: The servo motor has more than one feedback function, namely, one coder. The stepping motor and servo motor are both the receiver of the upper machine pulse or the analog model to control the rotation Angle and speed of the motor. But the step motor has no feedback function to run the ring. The servo motor has the encoder feedback, for the closed-loop operation. So the accuracy of the servo is higher than the step motor, and the accuracy of the servo motor depends on the encoder resolution.
