استپر موتور 1.5 آمپر 42BYGH47 مناسب برای پرینترهای سه بعدی

Description:
A stepper motor, also known as a step motor or stepping motor, is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor's position can then be commanded to move and hold at one of these steps without any position sensor for feedback (an open-loop controller), as long as the motor is carefully sized to the application with respect to torque and speed.
There are a wide variety of stepper types, some of which require very specialized drivers. For our purposes, we will focus on stepper motors that can be driven with commonly available drivers. These are Permanent Magnet or Hybrid steppers, either 2-phase bipolar or 4-phase unipolar.
Another thing to consider is how the motor will interface with the rest of the drive system. Motors are available with a number of shaft styles Round or "D" Shaft, Geared shaft and Leadscrew Shaft.
The next thing to consider is the positioning resolution you require. The number of steps per revolution ranges from four to 400. Commonly available step counts are 24, 48 and 200.
Resolution is often expressed as degrees per step. A 1.8° motor is the same as a 200 step/revolution motor.
The trade-off for high resolution is speed and torque. High step count motors top-out at lower RPMs than similar size. And the higher step-rates needed to turn these motors results in lower torque than a similar size low-step-count motor at similar speeds.
Another thing to consider is how the motor will interface with the rest of the drive system. Motors are available with a number of shaft styles Round or "D" Shaft, Geared shaft and Leadscrew Shaft.
There are three main types of stepper motors Permanent magnet stepper, Variable reluctance stepper, and Hybrid synchronous stepper.
