Brushless DC motor (BLDC)
Achieve the next level of efficiency
Today, a growing number of applications rely on a brushless DC (BLDC) motor. These range from medical equipment and home appliances to building controls and industrial automation. In each instance, a BLDC motor is chosen for its numerous advantages, such as:
- Highest efficiency
- Smaller motor size
- Light weight
- Longer lifetime
- No maintenance
- No sparking

Key BLDC challenges
Though a BLDC motor is fairly efficient by nature, designers today face mounting pressure to further enhance their design’s efficiency and stand out on the competitive market. This can be achieved, for example, by reducing overall energy consumption and optimizing thermal management. Reducing the system size and decreasing maintenance can also help produce desirable results.
To overcome these key challenges and design a more efficient brushless DC motor, you need a competent partner by your side. Infineon’s product offer for BLDCs provides exactly what you are looking for, from power switches, to microcontrollers and dedicated motor control ICs, to gate drivers, to sensors.

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.
