RS PRO Hybrid, Permanent Magnet Stepper Motor, 17.5mNm Torque, 3.96 V, 1.8°, 20.2 x 20.2mm Frame, 4mm Shaft

For highly accurate position control in industrial devices, choose this hybrid stepper motor from RS PRO. It's controlled by discrete electrical pulses rather than continuous current and stays in a particular position as long as power is supplied. This means it doesn't accumulate errors during operation, so it's easy to use and maintain in variable speed devices, such as CNC (Computerised Numerical Control) machines and 3D printers.
This motor uses a permanent magnet, so it maintains full torque even at low speeds, which makes it highly efficient. It's also very easy to maintain and doesn't produce much noise during operation.
Stepper motors are typically connected to open-loop systems so they can be controlled digitally for precise handling. This unit is useful in both holding and positioning applications, such as in packaging machinery, fluid dispensing pumps and lab equipment.

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:

Robotics
Paper feed mechanisms
Teletype printers
Small machine tools
Computer peripherals
X-Y plotters
