網頁A step motor or stepping motor is called a stepper motor in which the single rotation is divided into a number of steps. Each step is being calculated by an angle. The step angle can be varied as per the design of the motor. It has a permanent magnetic rotating shaft called the rotor and stationary electromagnets surrounding the rotor called ... 網頁2024年4月11日 · Stepper motors, like any other permanent-magnet motor, generate a torque that has a component that just comes from the motor construction, and a component that's proportional to current, not voltage. They also generate back EMF. So if you apply a constant-voltage step and move the motor rapidly, the available torque would go down.

"網頁Step 2: Calculate load parameters. To properly size a motor you will need to calculate both torque and inertia. A parameter that is sometimes overlooked is the load moment of inertia or simply put load inertia. By definition the moment of inertia is a measurement of how difficult it is change the rotational velocity of an object. " - Stepper motor equations
