Steps 1, from the Angle of choosing motor is apart from the Angle of demand depends on the accuracy of load, the load of the minimum resolution conversion to the motor shaft, each equivalent motor should go how many viewpoints (Contains the deceleration)。 Step motor of pitch Angle should be equal to or less than the point of view. The current market shangbu step into motor is usually from the Angle of 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. 2, the choice of static torque stepper motor dynamic torque for a while it is difficult to conclude that usually we concluded that the static torque of the machine. Static moment chosen is based on motor operating load, the load can be divided into the inertial load and load the two conflict. Single inertial load and load of a single conflict does not exist. Direct starting (Usually by low speed)When two kinds of load to think, to speed up when starting the primary thinking inertia load, load constant speed transport distances just thinking about conflict. Usually, the static torque load of 2 - should be conflictGood within 3 times, once selected, static torque motor frame and length can be concluded that down,How much scale)3, select the same static torque motor, current, because the current parameter, the operating characteristics different is very big, can be based on the torque-speed characteristic curve, the discriminant of the motor current (Refer to the drive power supply, and the drive voltage)4, torque and power conversion step motor is usually used in a wide range speed adjustment, its power is changed, usually only used to measure torque, torque and power conversion is as follows: P = Ω m. Ω = 2 PI n/P = 2 PI 60 nM / 60 P as the power unit for tile, its Ω per second angular velocity, the unit as the radian, n for RPM, M for the moment unit is n · M P = 2 PI fM / 400 (Half step operation)F pulses per second -PPS)（2), step motor using the attention point 1, stepper motor - used in low speed occasionsAre no more than 1000 turn, RPM (0. 9 degrees 6666 PPS), the best - in 10003000PPS(0. 9 degrees)Apply, but a deceleration device to in the work, this moment motor operation with high efficiency, low noise. Step 2, step motor best don't use the whole situation, the whole step in oscillation. 3, because the former history reason, as long as the nominal for the 12 v voltage of the motor using 12 v, the other motor voltage value is not driving voltage v, can choose driving voltage (according to the driveProposition: SL57 choose dc 24 v -Dc 50 v, 36 v, SL86 choose SL110 choose higher than dc 80 v)12 volts, of course, in addition to the 12 v constant voltage driver also can choose other drive power supply, but want to think about temperature rise. 4, big moment of inertia of the load should be selected motor frame size larger. 5, the motor in the high speed and large inertia loads, usually is not starting operation speed, and choose frequency speed gradually rise, a step motor do not break, two together can reduce noise can progress to suspend the position precision. 6, high precision, after mechanical slow, progressive motor speed, or selects high fine fraction drive to deal with, also can choose five phase motor, but the price is more expensive, the whole system manufacturers, it is screening is just rubbish. 7, the motor should not be within the range of oscillation, voltage, current, or can be altered if necessary add some damping treatment. In 600 PPS (8, motor0. 9 degrees)The following assignments, should choose small current, large inductance, low voltage to drive. 9, should follow to choose after motor driven first principles. 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.
