'Linear stepping motor'
Is an induction motor, its working principle is to use electronic circuits, it will become a timing DC power supply, multi-phase timing control current, the current stepping motor power supply, the stepping motor can drive the stepping motor normally, and the power sharing and multi-phase timing controller are adopted. Although'Linear stepping motor'
It has been widely used, but as a general stepping motor, it has not been used as a DC motor. AC motor is used in practice.
It can only use double-loop pulse signals, and the power driver circuit forms a control system.
Therefore, stepping motors are good but not easy. They involve many professional knowledge in the fields of machinery, electricity, electronics and computers.
As a performance component, stepping motor is one of the key mechatronics products and is widely used in various automatic control systems.
With the development of microelectronics and computer technology, the demand for stepping motors has been applied to various fields of the national economy with the passage of time.
The control of the stepping motor can only be operated by digital signals. The pulse drives the stepping motor. In a short time, the control system will issue several pulses, I . e. the pulse frequency is too high, which will lead to the stall of the stepping motor.
In order to solve this problem, it is necessary to choose the way of acceleration and deceleration.
In other words, when the stepping motor is started, it gradually rises to give the pulse frequency, and the pulse frequency demand deceleration gradually decreases. In other words, we often say'Deceleration'Law. 'Linear stepping motor'
The transmission rate varies according to the change of the input pulse signal.
In theory, in order to drive the pulse, the stepping motor rotates a stepping angle (Break when subdividing the stepping angle).
In fact, if the pulse signal changes too fast, the magnetic reaction between the rotor and the stator will not follow the change of the electrical signal due to the damping effect of the stepping motor inside the back electromotive force, resulting in stall and out-of-step.
