Permanent magnet synchronous motor (PMSM)
In our fast-paced world, permanent magnet synchronous motors – commonly used in industrial automation for traction, robotics or aerospace – require greater power and heightened intelligence. Cutting-edge semiconductor solutions from Infineon promise and deliver highest-possible quality and the most innovative technologies. Turn to our software tools to reduce the complexity and cost of integrating specific feature sets into your systems. Within Infineon’s wide portfolio, you'll find the right products, application kits and support to optimally control permanent magnet synchronous motors. See additional motor control applications here in battery powered applications, home and building and industrial automation.
The permanent magnet synchronous motor is cross between an induction motor and brushless DC motor. Like a brushless DC motor, it has a permanent magnet rotor and windings on the stator. However, the stator structure with windings constructed to produce a sinusoidal flux density in the airgap of the machine resembles that of an induction motor. Permanent magnet synchronous motors' power density is higher than induction motors with the same ratings since there is no stator power dedicated to magnetic field production. Today, these motors are designed to be more powerful while also having a lower mass and lower moment of inertia.

Key characteristics permanent magnet synchronous motor
- Close relative of the brushless DC motor
- Permanent magnet rotor and windings on the stator
- Sinusoidal back electromagnetic field (EMF) waveforms of the windings
- Controlled with sinusoid waveforms: matches the back EMF waveform of each winding
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.
XMC drive cards for low- and high-voltage operating ranges
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.
