Description of 57mm stepper motor
- 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.
- Online testing of technical parameters to ensure the consistency of data product parameters
- The Fulling product line is sold to major manufacturing Companies for Industry of automation, medical andhealth care equipment, printer machine, packing device,Information Technology,household appliance
product,AGV and automobile.
- 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
-
Accurate Speed Control
The rotational speed of the stepping motor can be precisely controlled ,By controlling the frequency of the electric pulse.
Features :
- Input pulse decides the rotation angle of the motor.
- High accuracy of around 3 to 5% a step.
- Provides good starting, stopping and reversing.
- Control of this motor is less costly because of exclusion of complex control circuitry.
- The speed is proportional to the frequency of the input pulses.
Note :
- The Nema17 5.6kgcm Stepper motor dimensions and weight may have ±2% error.
- Resonances can occur because of improper instalment.
- Not easy to operate at extremely high speeds.
- The cable comes with Motor has connector from one end to connect it to the motor while another end of cable is open for soldering
Advantage of Product
- Prostepper motor use of a unique stator the chnology to ensure that the motor stator teeth grinding and smooth high accuracy of the hole, the work of the process of speed stability is not lose step
- Prostepper motorcoil is made of 100% pure copper enameled wire , advanced winding threading process, copper wire is evenly arranged, good overall motor stability , the long time does not appear deformation and noise and so on.
- High quality motor steel, the load on the shaft can produce high torque the inertia ratio, and can eliminate, the system error due to the use of reduction gears
