Under the condition of non-overload, the low-frequency vibration phenomenon determined by the working principle of the stepping motor is very unfavorable to the normal operation of the machine. Both copper loss and iron loss will be expressed in the form of heating, thus affecting the efficiency of the motor. Stepper motors generally pursue positioning accuracy and torque output, and their efficiency is relatively low. When the stepper motor works at low speed, its main feature is that it will not lose step. Under the specified long-term and short-term mechanical load, the output displacement of the stepping motor is proportional to the number of input pulses. Stepping motor is an open-loop control element stepping motor device that converts electrical pulse signal into angular displacement or linear displacement. However, stepping motors are not like ordinary DC motors. Stepping motors need to be driven by special stepping motor drivers, which consist of pulse generation control unit, power drive unit, protection unit, etc. The power drive unit amplifies the pulse generated by the pulse generation control unit. The operation performance of the stepping motor is closely related to the control mode. The AC motor is normally used. Servo Motors also control the number of pulses. Stepping motors have strict requirements on speed and position when used. The angular displacement can be controlled by controlling the number of pulses emitted, thus achieving the purpose of controlling the displacement; At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, thus achieving the purpose of speed regulation. The rotation angle of the rotor strictly corresponds to the number of input pulses, and the rotation speed is proportional to the pulse frequency. By controlling the number and frequency of input pulses and the power-on sequence of each phase winding of the motor, the rotation angle, rotation speed and rotation direction can be controlled. In the process of using the stepping motor, the temperature will continue to increase with the increase of the use time. After reaching a certain level, the temperature will not increase, at this time, the load on the equipment is very large, which will lead to the wear and tear of the equipment. Attention should be paid to the decrease in temperature. The stepping motor controls the rotation angle by controlling the number of pulses. One pulse corresponds to one step angle, but there is no feedback signal, the time required for the motor to rise from the starting frequency to the high operating frequency or from the high operating frequency to the starting frequency. Designers of stepping motors integrate electronic systems with motors, which can reduce cable wiring, simplify the implementation process, and realize cabinet-free machines. 42 series two-phase stepping motor, two-phase Hybrid Stepping Motor, step angle is 1. 8 °. After detailed testing and comparison, ruite electromechanical finally selects a stepping motor with high performance, high quality and high cost performance to help you design your automation equipment. Welcome all manufacturers to call and write, contact business! Cooperation and mutual benefit! Give back to you with exquisite technology and sincere service. The stepping motor has a technical parameter: no-load starting frequency, that is, the pulse frequency that the stepping motor can start normally under no-load condition. If the pulse frequency is higher than this value, the motor cannot start normally, loss of step or blockage may occur. The magnetic field will drive the rotor to rotate at an angle, so that the direction of a pair of magnetic fields of the rotor is consistent with the magnetic field direction of the stator. When the stator's vector magnetic field rotates an angle. The working principle of the motor is the effect of the magnetic field on the current, which makes the motor rotate. Each input of an electric pulse, stepping motor is classified according to the structure: stepping motor is also called pulse motor, so this stepping motor is a three-phase stepping motor. Stepping Motor is suitable for running at low speed. When the speed is accelerated, if the working speed of the motor is higher or the response requirement is faster, then the voltage value is also higher, however, note that the ripple of the power supply voltage cannot exceed the large input voltage of the driver, otherwise the driver may be damaged. The noise of stepping motors will increase significantly, and other economic indicators will decrease significantly. Stepping all-in-one machine is an actuator that converts electrical pulses into angular displacement. The driver uses real sine wave, vector and filtering methods to control the current. Generally speaking, when the driver of the stepping all-in-one machine receives a pulse signal, the Hybrid Stepping Motor refers to the advantages of mixing permanent magnet and reactive type. Its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, thus achieving the purpose of accurate positioning; At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency, thus achieving the purpose of speed regulation. The vibration frequency is related to the load and the performance of the driver. It is generally believed that the vibration frequency is half of the no-load take-off frequency of the motor. This kind of low-frequency vibration phenomenon determined by the working principle of stepping motor is very unfavorable to the normal operation of the machine. The power supply drive circuit is composed to form a control system. Set the direction to rotate one called'Step angle' The rotation of the fixed angle is carried out step by step with the fixed angle. Usually, the stator core is used to punch the rotor core by punching the backward silicon steel sheet inner circle. Generally, the rotor core of a small asynchronous motor is directly pressed on the rotating shaft, and large and medium-sized asynchronous motors ( The diameter of the rotor is 300 ~ 400mm or more) The rotor core is pressed on the rotating shaft with the help of the rotor bracket.
