Five steps for selection of ruite stepping motor. Ruite electromechanical is an enterprise mainly engaged in customization of stepping motor, stepping motor driver, open closed loop stepping motor, linear stepping motor and servo motor, today, let's take a look at the ruite stepping motor. Step 1: the holding torque of the stepping motor is equivalent to what the traditional motor said. 'Power'. Of course, they have essential differences.
The physical structure of stepping motor is completely different from ordinary AC and DC Motors, and its output power is variable.
Usually, which type of stepping motor is selected according to the required torque. Generally speaking, the torque is 0. 8n.
Below m, generally choose 28, 35, 39, 42; The torque is 1N. About m, it is more appropriate to choose 57 motor. The torque is several N.
In the case of m or larger, stepping motors of 75, 85, 86, 90, 110, 130 and other specifications with larger torque should be selected. At the same time, we should also consider the speed of the motor.
Because the output torque of the motor is inversely proportional to the rotating speed.
Step 2: Stepping Motor no-load starting frequency, generally called'Empty starting frequency'.
This is a very important indicator for purchasing stepping motors.
If it is required to start and stop frequently in an instant, and the rotating speed is about 1000 rpm or higher.
It is best to choose reactive or permanent magnet stepping motorsEmpty starting frequency'Both are relatively high.
Step 3: phase number selection of stepping motor. Many customers pay little attention to this content, and most of them buy it casually.
In fact, motors with different phase numbers have different working effects.
The more the number of phases, the smaller the step angle can be, and the vibration at work is relatively small.
In most occasions, two-phase, three-phase and five-phase hybrid stepping motors are used more often.
In the working environment of high speed and large torque, it is very practical to choose a three-phase stepping motor.
Step 4: waterproof and anticorrosive stepping motor can be waterproof and oil-proof, suitable for some special occasions. For example, underwater robots need to drain water motors.
75BYG series stepping motors are mostly waterproof.
For special purpose motors, it is necessary to select them accordingly.
Step 5: stepping motors with special specifications usually need to communicate with manufacturers and be processed and customized within the scope permitted by technology.
For example, the diameter, length, and extension direction of the shaft.
