Like most linear motors, a linear stepper motor is essentially a variation of the rotary design, cut radially and laid out flat. Similar to their rotary counterparts in operation and performance, linear stepper motors are 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). Unlike other linear motor designs, in a linear stepper motor, the platen is a passive component—a steel (or stainless steel) plate with slots milled into it. The forcer contains laminations with slotted teeth, motor windings, and a permanent magnet. The teeth of the forcer concentrate the magnetic flux that is created when current is applied to the coils. The forcer teeth are also staggered in relation to the platen teeth—typically by ¼ tooth pitch—to ensure that constant attraction is maintained and that the next set of teeth will come into alignment as current is switched in the coils. For each full step of the motor, the forcer moves ¼ tooth pitch.

  • 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.

A: Except special order. For samples usually 7-15 working days . for batch order . usually 20-25days.



7.Stepper Motor Applications

  • As the stepper motor are digitally controlled using an input pulse, they are suitable for use with computer controlled systems.
  • They are used in numeric control of machine tools.
  • Used in tape drives, floppy disc drives, printers and electric watches.
  • The stepper motor also use in X-Y plotter and robotics.
  • It has wide application in textile industries and integrated circuit fabrications.
  • The other applications of the Stepper Motor are in spacecrafts launched for scientific explorations of the planets etc.
  • These motors also find a variety of commercial, medical and military applications and also used in the production of science fiction movies.
  • Stepper motors of microwatts are used in the wrist watches.
  • In the machine tool, the stepper motors with ratings of several tens of kilowatts is used.
