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.
Example application for stepper motor control and drives
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
The Eval 5kW TO-Leadless evaluation board makes it easy to familiarize oneself with Infineon’s Power MOSFET OptiMOS™ 100V in the new TO-Leadless package. This new package is optimized for high-current applications, such as forklifts, light electric vehicles (LEV), PoL (Point of Load) and low-speed cars.
The XMC1000 and XMC4400 motor control application kits are ready-made evaluation kits for 3-phase drives. These two kits are best suited to customers looking for a motor control plug&play experience. Both kits have a similar setup with a microcontroller board, the respective 24V power board including n-channel OptiMOS™ power transistors and a 3-phase gate driver EiceDRIVER™ from Infineon, rounded off with a brushless DC motor. Both kits are supported by the DAVE™ Motor Control Apps library, including sinusoidal and block commutation as well as various position detection and sensing schemes with encoder, Hall sensors and shunts. The XMC4400 Motor Control Application Kit also includes a resolver interface.
Our DC motor control shield is one of the first high current motor control boards being compatible to Arduino as well as to Infineon’s XMC1100 Boot Kit. The DC motor control shield is capable to drive two uni-directional DC motors (half bridge configuration) or one bi-directional DC motor (H-Bridge configuration).
The XMC1300 and XMC4400 drive cards are microcontroller boards with galvanic isolation for evaluating 3-phase drives of up to several kilowatts. These two drive cards are best suited to customers looking to experience XMC microcontrollers and DAVE™ Motor Control Apps library with their power board/ existing Infineon power boards and their own motor. The debug interface is isolated from the XMC microcontroller and position detection interfaces in order to guarantee safe operation during software development. The XMC1300 drive card can control one 3-phase drive, while the XMC4400 drive card can control up to two. The DAVE™ Motor Control Apps library, together with xSPY for software development and motor parameterization, is the best fit for the XMC1300 and XMC4400 drive cards.
