20 Mm Micro Stepper Motor Matched With Gearbox 18°/Step 2 Phases

20 Mm Micro Stepper Motor Can Be Matched With Gearbox 18°/Step 2 Phases

Description

This permanent magnet stepper motor is 20mm in diameter, has a torque of 60gf.cm, and can reach a maximum speed of 3000rpm.
This motor can also be added to the gearbox, the motor step angle is 18 degrees, that is, 20 steps per revolution. When the gearbox is added, the motor deceleration effect rotation angle resolution can reach 0.05~6 degrees. Applicable to many needs, precise control of the rotation position.
The coil resistance of the motor is 9Ω/phase, and it is designed for low drive voltage (about 5V DC). If the customer wants to drive the motor at higher voltage, we can adjust the coil resistance to match it.
In addition, there are two M2 screws on the cover of the motor, they are used to fix with the gear box. Customers can also use the screws to fix this motor to other parts.
Its connector is 2.0mm pitch (PHR-4), and we can change it to another type if the customer wants to.
Therefore, this product can be used where precise position control is required. It can be generally used in medical equipment, printers, automation equipment, robots, etc.

Features & Advantage

1. High precision positioning
Since steppers move in precise repeatable steps, they excel in applications requiring precise
positioning, by the number of steps the motor moves
2. High Precision speed control
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.
3. Pause and holding function
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.
4. Long life & low electromagnetic interference
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.

Working principle of stepper motor

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.
