Product Description
This is a pm reduction stepper motor with a diameter of 28mm,Out put gear with friction clutch.
The gear ratio of this motor is 16:1, 25:1, 32:1, 48.8:1, 64:1, 85:1.
The motor has a step angle of 5.625°/64 and is driven by 1-2 phase excitation or 2-2 phase excitation.
Rated voltage: 5VDC; 12VDC; 24VDC.motor connection wire and connector wire specifications UL1061 26AWG or UL2464 26AWG,The motor is mainly used in sanitary ware, thermostatic valve, hot water faucet, intelligent toilet, air conditioner, automatic adjustment of water temperature and flow, door lock, water purifier and a series of household appliances.
Also, other fields that require precise control can be realized. Due to the realization of open-loop control, low-cost position control is realized.
The price of this product can be lower than other products due to the high production volume.
In addition it has a gear on the face, the general gear material is POM (plastic), we can also replace it with a metal gear, but this will increase the cost.

Since steppers move in precise repeatable steps, they excel in applications requiring precise
positioning, by the number of steps the motor moves
Precise increments of movement also allow for excellent control of rotational speed for process
automation and robotics. The rotational speed is determined by the frequency of the pulses.
With control of the drive, the motor has lock function (there is current through motor windings, but
the motor does not rotate), and there is still a holding torque output.
The stepper motor has no brushes, and does not need to be commutated by brushes like a brushed
DC motor. There is no friction of the brushes, which increases the service life, has no electric sparks, and reduces electromagnetic interference.
The drive of the stepper motor is controlled by software. When the motor needs to rotate, drive will
apply the stepper motor pulses. These pulses energize stepper motor's in a specified order, thereby
causing the motor's rotor to rotate in a specified direction (clockwise or counter clockwise). So as to
realize proper rotation of the motor. Each time the motor receives a pulse from the driver, it will rotate by a step angle (with full-step drive), and the rotation angle of the motor is determined by the number of driven pulses and step angle.
