Stepper motor

For industrial automation and office printing machines, the cost-efficient stepper motor is often the ideal choice. But not all stepper motors are equal. With high quality and reliable solutions from Infineon – such as our highly integrated stepper driver ICs – you can enhance performance and increase energy efficiency. Or integrate microcontrollers and benefit from diagnostic features for excellent operating stability with minimal maintenance. Look through our wide portfolio of products and low-voltage motor control application kits and find the best-fit solution for your stepper motor systems. See additional motor control applications here in battery powered applications, home and building and industrial automation.

A stepper motor divides a full rotation into a number of discrete steps. The motor's position can then be commanded to move and hold at one of these steps. Once stopped, the stepper holds the load steady with a holding torque. Most stepper motors employ a doubly salient design with teeth on both the rotor and stator structures. Like a brushless DC or permanent magnet synchronous motor, the permanent magnets are on the rotor and the electromagnets are in the stator.

Key characteristics stepper motor

  • Inexpensive: the rotor contains no winding slip rings or commutator
  • Easy to position: moves in steps based on pulses supplied to the stator windings
  • Direction of rotation changes by reversing the pulse sequence
  • Speed control through frequency of pulses or pulse rate
