1.8° 1A 3kg.cm 320mm 4wires Nema17 linear stepping motor

Similar to their rotary counterparts in operation and performance, a linear stepper motor is typically run as open-loop systems and are capable of providing high resolution at high speeds and accelerations.The linear stepper motor almost exclusively employs a hybrid design, with two main parts—a base (also referred to as a platen) and a slider (also referred to as a forcer).

7.Advantages of Hybrid Stepper Motor

• 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.
