Choose to keep the torque
keep the torque is also called static moment, refers to the stepper motor power but no turns, the stator ( : the stator core, stator windings and the frame) Locked rotor torque. Due to the low speed of the stepper motor torque is close to the holding torque, the stepper motor torque and fast attenuation with the increase of speed, the output power also along with the increase of speed change, so keep measure stepper motor torque is one of the important parameters of load capacity. For example, generally do not add that when it comes to N. M stepper motor, which can be understood as holding torque is N. m。
2. Select phase number
two phase stepper motor of low cost, step away from the Angle of less. 8 degrees, when low speed vibration of large, high speed torque reduce fast, suitable for high speed and the precision and stability requirement is not high circumstance; Three-phase stepper motor step Angle. 5 degrees, vibration is smaller than two phase stepper planetary gear motor, the performance is better than two phase stepper motor at low speed, high speed of thirty percent higher than two phase stepper motor to 50, suitable for high speed and requiring higher precision and stability; Five phase stepper motor step Angle smaller, good performance at low speed in three phase stepper motor, but the cost is high, suitable for low speed section and requiring higher precision and stability. Stepper motor driver stepper motor can't directly to the power frequency ac or dc power supply work, and must use a dedicated driver, as shown, it is controlled by pulse generating unit, power drive unit, protection unit, etc. Figure midpoint line surrounded by two units can be done with microcomputer control.
3. Select step-motor
should follow the principle of first to choose after motor drive, first clear load characteristic, and then by comparing the different type of static torque and torque of stepping motor frequency curve, to find and load characteristics of stepping motor to match; Accuracy requirement is high, should adopt mechanical reduction gear, to make the motor work in high efficiency, low noise; Keep the motor working in vibration area, if must by changing the voltage, current, or to increase the damping of the methods to solve; Power supply voltage, it is suggested that take dc 24 v - 57 motor 36 v, 86 motor take 46 v dc, 0 to higher than the dc 80 v; Big moment of inertia load elected into the seat number larger motor; Large inertia load, working at high speed, motor and should be taken to gradually rise frequency speed, in order to avoid out of step motor, reduce noise, improve a halt when the positioning accuracy; In view of the stepper motor torque generally under 40 nm, beyond the scope of this moment, and run faster than 000 RPM, which should consider to choose servo motors, general ac servo motor can be running at 3000 RPM, cocoa the dc servo motor running at 0000 RPM. Stepper motor driver in order to further improve the drive systems of high frequency response, frequency boost power driver interface can be used up. The interface provided by the winding voltage and the operating frequency of the motor into linear relationship. Its main circuit is actually a switch regulated power supply, use of frequency - Voltage converter, drive pulse frequency conversion into dc level, and the level to control switch regulated power supply input, this constitutes a frequency feedback power driver interface. Stepper motor is a kind of induction motor, its working principle is the use of electronic circuit, direct current (dc) into time-sharing power supply, multiphase sequential control current, in this current for stepper motor power supply, step motor to work properly, is time-sharing power supply for step motor drive, multiphase timing controller.
4. Select the drive and fine fraction
step not to choose the whole state, because the whole step state vibration; As far as possible choose low current, large inductance and low voltage drives; Is greater than the working current of the drive, in need of low vibration or ( C) When blending subdivision drive, with high voltage type for large torque motor drives, in order to obtain good high speed performance; Actually used in motor speed is usually high and the requirements for precision and stability is not high, don't have to choose the high fine fraction drive, in order to save cost; Actually used in planetary gear motor speed conditions are usually very low, should choose larger fine fraction, to ensure smooth operation, reduce the vibration and noise; In short, when choosing the fine fraction, stepping motor drive must be taken into account comprehensively the actual running speed, load torque range, speed reducer Settings and the requirements on accuracy, vibration and noise.
In the office, various are considered essential since they are used to achieve particular tasks in the office. Among these , electric motor suppliers, planetary gear motor, and types of gear reducers are widely used.
Many websites provide additional information on the topic of electric motor suppliers. One such site worth visiting is Zhenyu Transmission.
The planetary gear motor electric motor suppliers has significantly numerous benefits over other types of gear reducers systems, which makes it first choice for planetary gear motor.
In business, electric motor suppliers means cultivating brand loyalty; once someone is working with a product or using a service, they are more likely to commit to paying for Zhenyu again.
