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.
