Stepper motor magnets
A stepper motor is a motor that converts electrical signals into mechanical action. The rotation angle and speed of the motor are controlled by the electrical signal (number of pulses) and its frequency. According to the characteristic of rotating according to the given electrical signal, it can realize not only continuous operation but also intermittent drive, positive and negative rotation and other functions. Therefore, it is often used in the control and positioning of office automation printers, fax machines and other equipment, computer peripheral equipment, electronic digital equipment, laser engraving machines and other precision equipment.
There are several angular errors in tiny stepper motors. One is a flaw in the motor itself -- mechanical and magnetic -- because motors don't have a perfect sinusoidal current-to-position transfer function. Even if you apply perfect sine and cosine currents to the motor, the motion is not perfectly linear.
A stepper motor with an outer diameter of 3~6 mm needs to obtain 20~40 steps per circle, so as to ensure the high resolution and high output torque of digital products, as well as fast positioning control and automatic anti-shake, fast and automatic Focusing, and to ensure quietness during the focusing process, this is to strictly test the step angle accuracy of the micro-stepping motor and the magnetization pole width, pole difference, and magnetic declination of the permanent magnet.
In the modern life that requires informatization and high efficiency, data products are required to focus instantly to complete the capture, so the focusing speed is undoubtedly directly determined by the motor. The more powerful the motor, the faster the focusing speed. Therefore, the stepper motor has a very high rotation speed and precision, which is closely related to the dimensional accuracy of the rare earth permanent magnet, the magnetization technology, and the process stability of the magnet production. The stepper motors produced by our company have been following the steps of customers, from 3x zoom to 5x zoom, and have been upgraded to today's 30x zoom requirements, and continuously improve the manufacturing level and processing accuracy of rare earth permanent magnets to respond to the new generation The high requirements of the products are widely used in Nikon, Canon, SONY, Olympus and other photographic equipment.
