Description of Gear Box Stepper Motor
1. Accurate position Control
The angular displacement of the stepping motor can be precise
controlled by the number of electrical pulses.Angle accuracy can be
controlled within ±0.09°without any feedback devices.
2. Longer Life
Stepping motor is a mechanical structure,which does not need be
changed by electric brush or Hall sensor,thus reducing the
probability and increasing the motor life.Stepping motor life
usually determined by the life of the bearing.
3. Strictly control the production of parts to improve the quality
of parts.
4. The material is selected from well-known manufacturers at home
and abroad. The advantages are light weight, good heat dissipation
performance, good thermal conductivity, die-casting, good
plasticity, higher elongation than iron, low noise, good motion
stability, the disadvantages are high price, low hardness

Gear Box 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.
Gear Box Stepper Motor features
- Smooth surface
- Long lasting life
- 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.
