Two Phase Hybrid NEMA34 Stepper Motor With Brake 1.8 Degree
Product description
Automatic assembly line
Automatic assembly line, improve production efficiency, low cost
without human operation, one line down intelligent mechanical
automatic assembly
Forward/Reverse Rotation,Pause and Hold
The forward /reverse rotation of the stepping motor can be
controlled by the input sequence of the controlled electric pulses.
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

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
- Speed/Torque Characteristics(Reference Value)
Tips: How to overcome the vibration and noises of 2-phase hybrid
stepper motor when rotating at low velocity?
The vibration and noise of the stepper motor rotating at low
velocity its the intrinsic defects, which can be generally overcome
by adopting following schemes:
1. If the stepper motor works at resonance region, the
resonance region can be evaded by changing mechanical transmissions
such as velocity ratio.
2.Use subdivided driver, which is the most common and simple
method.
3.Replace for the stepper motor with smaller stepping angle, like
3-phase or 5-phase stepper motor.
4.Replace for AC servo motor, which can nearly overcome vibration
and noise, but the cost is quite high.
5.Add magnetic damper to the shaft of motor, such product has been
available in the market, but the mechanical structure is changed a
lot.
