What are the advantages and disadvantages of stepping motors? What are they suitable for?
1. the angle of rotation of the motor is proportional to the number of pulses;2. when the motor is stopped, it has the maximum torque (when the winding is exciting);
Mainly applies to:First, the stepper motor is mainly used for positioning applications, such as wire cutting workbench drag, tufting machine working table (pore location), packing machine (length), basically involves the positioning of the occasion are obtained;Second, widely used in ATM machines, printing machines, engraving machine, photo machine, spraying equipment, medical instruments and equipment, computer peripherals and mass storage equipment, precision instruments, industrial control systems, office automation, robotics and other fields, especially suitable for the requirements of stable operation, low noise, fast response, long service life, high output torque applications;Third, stepper motor is widely used in computer embroidery machine and other textile machinery equipment, characteristics of this kind of stepping motor is holding torque is not high, frequent start fast reaction speed, low noise, stable operation, good control performance and low cost;Generally speaking, stepper motors are widely used in mechatronic products because of their low inertia, high positioning accuracy, no accumulation error and simple control.
7., the load is directly connected to the rotating shaft of the motor, and it can rotate synchronously at very low speed.8. as the speed is directly proportional to the pulse frequency, there is a relatively wide range of speed.
4. excellent start stop and reverse response;5. because there is no brush, the reliability is high, so the life of the motor only depends on the life of the bearing;The response of the 6. motor is only determined by the digital input pulse, so open-loop control can be adopted, which makes the structure of the motor simpler and less expensive to control;
