stepper motor Electrical pulse signal
I believe that industry people know that stepper motor has been widely used, it can control the number of pulses to control the angular displacement, so as to achieve the purpose of accurate positioning, then you know the benefits of stepper motor? The following is explained by Xiao Bian for you.
1, the angle of rotation of the motor is proportional to the number of pulses.
2, when the motor stops with the maximum torque (when the winding excitation).
3, excellent start and stop and reverse response.
4, because there is no brush, high reliability, so the life of the motor depends only on the bearing life.
5, only the load directly connected to the motor shaft can also be very low speed synchronous rotation.
6, because the speed is proportional to the pulse frequency, which has a wide range of speed.
Stepping motor is an open-loop control motor that converts electrical pulse signal into angular displacement or line displacement. It is the main executive element in modern digital program control system. It is widely used. Do you know the advantages of stepper motor? The following is explained by Xiao Bian for you.
1, precise position control, according to the number of input pulses to determine the angle of rotation of the axis.
2, can be stepless speed, according to the output pulse frequency, determine the speed of rotation of the shaft.
3, forward / reverse rotation, emergency stop and lock function, through the polarity of the change can control the axis forward or reverse rotation. In the case of a motor lock, the output of the torque is maintained.
4, low-speed conditions of high-precision position control, the party input low-frequency pulse, the motor shaft can still be very low speed rotation, without relying on the gear box to adjust the transmission, thus avoiding the power loss and angular position deviation.
5, longer life, do not like ordinary DC motor through the brush and commutator to adjust the phase, thereby reducing the friction, an increase of the motor life.
Stepping motor is an open-loop control motor that converts electrical pulse signal into angular displacement or line displacement. It is the main executing element in modern digital program control system. It is widely used, so you know the reason why the stepping motor is not allowed to be used ? The following is explained by Xiao Bian for you.
1, the requirements of the initial start speed is too high, more than the motor limit starting frequency, or too much acceleration, resulting in "lost step.
2, the motor motor power does not meet the system requirements.
3, the work of the device suffered interference.
4, the control system controller malfunction.
5, when the vote for the pulse, one-way operation accurate positioning, post-positioning after the deviation, and although the increase in the number of times the deviation of the product plot is more obvious.
6, the software design flaws.
7, the use of timing belt of the occasion, the software compensation too much or too little.
