Jinnuo Construction Hoist Motor

Q:What is the power supply of a two phase stepper motor?: We drive using the 50VDC driver such as EZM552 in the design, selection of power supply 36VDC DC power supply, two step to drive 57HS09 stepper motor, rated current is 2.8A, the power supply capacity can choose 36*2.8*0.7=70W, that is to say the power is greater than 70W

Q:What is the angle of pitch in a stepper motor and what does it have to do with the step angle?: 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.

Q:What is the difference between the stepper motor driver and the quiescent current setting to ON or OFF?: Two, induction type stepper motor working principle (I) response type stepper motor principle, because the reaction stepper motor working principle is relatively simple. The following describes the principle of three-phase reactive stepping motor.1, structure: uniformly distributed rotor with many small teeth, the teeth of the stator with three excitation winding, the geometric axis of the rotor tooth axis in orderwere staggered. 0, the 1/3, the 2/3, (two adjacent rotor tooth axis was the distance between the pitch to the said, A and 1) teeth aligned, B and 2 1/3 at right staggered tooth, C and 3 2/3 at right staggered tooth, 5 teeth and A'aligned (A' is A, the tooth the 5 is the tooth 1) below is out of the rotor:

Q:How do you calculate the time required to move the stepper motor?: You ask your executive to walk n times a minute, then the stepper motor, the number of turns a minute is 2n, the number of stepping pulse is 360*2n

Q:What are the differences between the two parameters of the maximum static torque and the positioning torque in the stepper motor?: The output power also varies with the speed, so keeping torque is one of the most important parameters to measure the stepper motor. For example, when people say that 2N.m stepper motor, in the absence of special instructions, refers to the torque of 2N.m stepper motor.

Q:Why does the torque of stepping motor decrease with the increase of speed?: As the frequency (or velocity) increases, the phase current of the motor decreases, resulting in a decrease in torque.

Q:How about a pulse moving distance of a stepping motor? Can you give a formula for example?: The second step is to determine if the motor driver is subdivided and subdivided, not to find out the fine fraction, so that you can look at the dial code on the drive. For example, the 4 subdivision, as mentioned above, is 200*4=800, which means that the 800 pulse motors are rotated for only one week

Q:I am debugging a stepper motor, just start the line can work properly, but after power failure again on the power will not turn, how do not turn, the amount of motor coil resistance is normal. Please expert guidance and guidance!: First, you check the connection again, the power supply, and so on, and the rest are OK's.,Second (focus) you check your drive's subdivision settings, current settings, and pulse input mode, whether or not it is set correctly. And the frequency that the controller sends out is too high?.According to estimates of what you say is why the stepper motor driver is not set, my analysis is the case, you may just be used in the operation, but you modify a setting of the drive, and then restart the driver after the final set to take effect, just your settings are incorrect.

Q:The principle of stepper motor, 2 phase, 5 phase is what meaning, where information?: There are three kinds of stepper motors: permanent magnet (PM), reactive (VR) and hybrid (HB).Permanent magnet stepping is generally two-phase, torque and volume of smaller, step angle is generally 7.5 degrees or 15 degrees;The reaction step is generally three-phase, and can achieve large torque output. The step angle is generally 1.5 degrees, but the noise and vibration are very large. In Europe and the United States and other developed countries, in 80s has been eliminated;

Q:How to determine the pulse number of stepping motor: 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. 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.
