Nema11 JK28HS 5mm DC Small Stepper Motor 430g.cm - 1200g.cm
6-17oz.in High Working Efficiency
Hybrid stepper motor is a combination of variable reluctance and
permanent magnet motor. The stator is electromagnetically
stimulated like variable reluctance stepper motor, and the rotor of
the stepper motor is axially magnetized like permanent magnet
stepper motor. This stepper motor is an actuator that converts
electrical pulses into angular displacement.

Stepper Motor 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.
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.
