Product description of hybrid stepper motor

• 1. Online testing of technical parameters to ensure the consistency of data product parameters
• 2.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
• 3. Stepper motors are economical, accurate, and easy to control, and they can operate reliably in a variety of environments (depending on the level of protection IP chosen) preferably in machines with additional enclosures or in clean environments
• Forward/Reverse Rotation,Pause and Hold
• 4.The forward /reverse rotation of the stepping motor can be controlled by the input sequence of the controlled electric pulses.
• In the case of the a stepping motor lock(the motor winding is energized,there is no external electric pulse command),the stepping motor can still maintain a certain torque output.
• 5. Mechanical size 100% meet the requirements, to ensure that there is no greater error in the use process

Note

The winding on this article is a 4 Wire Bipolar.

0.9° and 1.8° Hybrid Stepper Motors

1.8° Step Angle,The motors are directly compatible with the stepper motor drive boards and also drive either motor (if required) in the half step mode i.e. 0.9° per step resulting in higher resolution, greater performance stability and faster stepping rates. Direction, velocity, acceleration/deceleration can be controlled by a stepper motor controller.,Applying the correct electrical pulse sequence to the windings of the stepper motor results in a 1.8° step angle rotation of the spindle (i.e. 200 steps per revolution). When correctly loaded and driven these motors will produce discrete output steps. The number of steps and speed of rotation are determined by the number of pulses and frequency of the input signal. This provides an ideal method for speed and position control. The motors are directly compatible with stepper motor drive boards.,

Applications include:

1. Robotics
2. Paper feed mechanisms
3. Teletype printers
4. Small machine tools

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.

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
