Advantages of Stepper Motor:
- The rotation angle of the motor is proportional to the input pulse.
- The motor has full torque at standstill.
- Precise positioning and repeatability of movement since good
stepper motors have an accuracy of 3 – 5% of a step and this error
is noncumulative from one step to the next.
- Excellent response to starting, stopping, and reversing.
- Very reliable since there are no contact brushes in the motor.
Therefore the life of the motor is simply dependant on the life of
the bearing.
- The motor’s 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.
Our stepper motor are widely used in engraving machine, cutting
plotter, textile machine, 3D printer, medical devices, stage
lighting equipment, robot, CNC machine, music fountain and other
industrial automatic equipment.
Applications:
- Industrial Machines – Stepper motors are used in automotive gauges and machine tooling
automated production equipment.
- Security – new surveillance products for the security industry.
- Medical – Stepper motors are used inside medical scanners, samplers, and
also found inside digital dental photography, fluid pumps,
respirators, and blood analysis machinery.
- Consumer Electronics – Stepper motors in cameras for automatic digital camera focus and
zoom functions. And also have business machines applications,
computer peripherals applications.
Operation of Stepper Motor:
Stepper motors operate differently from DC brush motors, which
rotate when voltage is applied to their terminals. Stepper motors,
on the other hand, effectively have multiple toothed electromagnets
arranged around a central gear-shaped piece of iron. The
electromagnets are energized by an external control circuit, for
example, a microcontroller.
Quality assurance:
- 1.All stepper motors have CE and RoHS certification
- 2.All motors are tested by a toasting machine for 72 hours
- 3.All the motors will be shipped after testing
Stepper Motor Control by Varying Clock Pulses
- Stepper motor control circuit is a simple and low-cost circuit,
mainly used in low power applications. The circuit is shown in the
figure,
- A stepper motor is an electromechanical device it converts
electrical power into mechanical power. Also, it is a brushless,
synchronous electric motor that can divide a full rotation into an
expansive number of steps. The motor’s position can be controlled
accurately without any feedback mechanism, as long as the motor is
carefully sized to the application. Stepper motors are similar to
switched reluctance motors.
- The stepper motor uses the theory of operation for magnets to make
the motor shaft turn a precise distance when a pulse of electricity
is provided. The stator has eight poles, and the rotor has six
poles. The rotor will require 24 pulses of electricity to move the
24 steps to make one complete revolution. Another way to say this
is that the rotor will move precisely 15° for each pulse of
electricity that the motor receives.
