Stepper motors have step pitch Angle (Involves the phase number), static torque, and the current three major components. Once the three main factors to determine, stepping motor model is identified, then selecting the attention points should be what? step motor from the Angle of depends on the accuracy requirement of the load, the load of the minimum resolution (Equivalent)Conversion to the motor shaft, each equivalent motor should go how many Angle (Including reduction)。 Step motor of pitch Angle should be equal to or less than this Angle. Step shangbu into motor from the Angle of the market at present commonly 0. 36 degrees / 0. 72 degrees (Five phase motor), 0. 9 degrees / 1. 8 degrees (Second, the four phase motor), 1. 5 c / 3 c (Three-phase motor)And so on. in the four macro electrical engineer advises clients stepper motor and stepper motor selection of current indispensable, because of the different parameters of current, the running characteristic difference is bigger, also can be based on the torque-speed characteristic curve, the judgment of the motor current and so on. 1。 Stepper motor step had better not use the whole state, the whole step state vibration is big, it will affect the use effect; 2。 Stepper motor is applied in occasions - at low speedSpeed does not exceed 1000 RPM,0. 9 degrees 6666 PPS), the best - in 10003000pps(0. 9 degrees)Used between, through the reduction gear to make it work here, the motor work with high efficiency, low noise; 3。 The moment of inertia big load should choose motor frame size larger; 4。 Motor in the high speed and large inertia loads, generally not starting in her work, and use frequency speed gradually rise, a step motor do not break, two can reduce the noise at the same time can improve the positioning accuracy of stop; 5。 High precision, through mechanical reduction, increase the speed of the motor, and fine fraction is high drive to solve, also can use 5 phase motor, but its price is more expensive, of the whole system really produce such businesses is less, the limitation limits the further development of products; 6。 Motor should not work in vibration zone, if must be by changing the voltage, current, or add some damping solution; 7。 In 600, PPS (0. 9 degrees)The following work, should use small current, large inductance, low voltage to drive. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
