Hybrid Stepper Servo Motor Hs421 (42mm, 2Phase)

Q:The step motor only rings: The acceleration time is too short, and the traffic is blocked. The solution: adjust and slow down.

Q:What do you mean by step motor? Two phase stepping motor and three-phase step motor: It is not possible to do so at the moment, only each phase is directed by a certain order. Notice stepping in the name of the motor, step by step, electromagnetism is the electromagnetic relationship, electromagnetic objectivity. Stepping motor is only the tip of the iceberg. Don't feel abstruse and know the rules, you don't ask. The best don't ask such a low level question.

Q:How do you solve the screw sloshing of the straight line of the shaft?: Low load low speed setting small current, while high load revs require large current. There's no mathematical formula that is set by the actual situation, right

Q:How does the step motor equivalent set: First, we know the screw, the screw is 5mm, the spacing of the two wires is 5mm. 2, the step motor is 1.8 degrees 200 steps, and the walk is 200 by 1.8 = 360 degrees

Q:Can a pulse signal from a PLC be given two steps at the same time?: In the case of the PLC output, the driver capacity is sufficient to drive the two-channel pulse input. If a driver is with the same brand, or wiring principle is the same, the same input voltage range, generally no damage, feel free to use, but the best telephone consultation with the manufacturer's technical support. If the brand, model, different batches, or wiring principle, internal resistance is different, although also can meet, but on the need to pay attention to many, it is difficult to describe.

Q:When the PLC controls the step motor, the pulse number required to step into the motor will be included in the acceleration and deceleration phase: These 1, 000 impulses include the number of pulses in these four stages, not just a constant pulse

Q:What is the meaning of the step motor drive half flow setting and attenuation setting?: Stepping drive half flow is mainly in order to reduce the heating of the motor, are generally used in stepping driving system constant current control, which means great electric motor and motionless, flows through the winding current were set according to the current work, such motor in standby, will serious fever, if adopting automatic flow, can significantly reduce the fever when standby. Some drives now have a current size of half a stream and a half current, such as innast's EZM552. The attenuation is mainly aimed at the actuator of the control method of the hysteresis loop, which is divided into fast decay and slow decay. The electric inductance of general motors is more slowly and less than the hour, and if it is a large inductance motor, it will be much more.

Q:Doubt the speed of the step motor: Stepper motor speed is proportional to the pulse frequency, the pulse frequency, the higher the stepper motor speed also, but increases the pulse frequency although reached the acceleration effect, has lost moment. The reason for the decrease of the moment with the increase of pulse frequency: The two reasons for stepping into the motor are: One, the control pulse frequency is high, the acceleration of the rotor is less than the speed with which the motor stator spins the magnetic field. The stepper motor power supply design, the stator coil electric time constant is basic fixed, assumes that the time constant is 0.02 S (0.02 S charging to a maximum of 63%), if the stepper motor to accept pulse cycle is greater than 0.04 S (duty ratio is 50%, the frequency is less than 25 hz), of the stator coil which can gain enough energy to produce enough to drive the rotor torque. If the pulse frequency is too high, such as 50 hz (duty ratio is 50%, more than 0.02 S) pulse cycle, the stator coil for the charging time of just 0.01 S, about half of charging time, the torque is reduced a lot, the rotor can't keep up with the speed of the stator rotating magnetic field, each step behind the equilibrium position should be arrived, and farther and farther away from the equilibrium position. The accumulated result is a lost step. 50 hz frequency is too small, of course, this example is just for illustration purposes, casual said a number of solutions: 1, to reduce the pulse frequency, don't think that trouble, most debugging step motor is the process of adjusting the pulse frequency

Q:It's not enough to step into the motor: The force of the step motor is not enough, can raise its working voltage to solve.

Q:The speed range of the moving platform of the left and right movement of the screw and step motor: This is a funny question. You don't know the spacing of the screw thread, the motor model doesn't know, the rotation speed doesn't know, you know what the range is?
