NEMA 17 Stepper Motor 42BYGH 1.8deg,40mm 1.5A 17HS4401S 42N.cm 4-Lead

1.Description

        Stepper motors are a type of DC synchronous motor. Whereas the rotation of an induction motor is largely uncontrollable, the rotation of a stepper motor can be controlled with a remarkable degree of precision. Stepper motors can produce full, instantaneous torque - even from a standstill.     A stepper motor is driven by a DC voltage applied through a driver.     Commercially, stepper motors are used in floppy disk drives, flatbed scanners, computer printers, plotters, slot machines, image      scanners, compact disc drives, intelligent lighting, camera lenses, CNC machines, and 3D printers.

5.Advantages

• Low cost for control achieved
• High torque at startup and low speeds
• Ruggedness
• Simplicity of construction
• Can operate in an open loop control system
• Low maintenance
• Less likely to stall or slip
• Will work in any environment
• Can be used in robotics in a wide scale.
• High reliability
• The rotation angle of the motor is proportional to the input pulse.
• The motor has full torque at standstill (if the windings are energized)
• Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3–5% of a step and this error is non-cumulative from one step to the next.
• Excellent response to starting/stopping/reversing.
• Very reliable since there are no contact brushes in the motor. Therefore, the life of the motor is simply dependent on the life of the bearing.
• The motors response to digital input pulses provides open-loop control, making the motor simpler and less costly to control.
• It is possible to achieve very low-speed synchronous rotation with a load that is directly coupled to the shaft.
• A wide range of rotational speeds can be realized as the speed is proportional to the frequency of the input pulses.
