Brushless DC motor (BLDC)
Achieve the next level of efficiency
Today, a growing number of applications rely on a brushless DC (BLDC) motor, ranging from automotive to industrial applications. Moreover, BLDC motors are used in medical equipment, home appliances, building controls and industrial automation. In each instance, a BLDC motor is chosen for the numerous advantages it offers, including:
- Highest efficiency
- Small motor size
- Light weight
- Longer lifetime
- No maintenance
- No sparking
- Steady operation
- Variable speed

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.

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.
Infineon Embedded Power ICs offer various boards and kits to evaluate all functions and peripherals providing access to all device I/Os. 3-phase bridge driver IC (TLE987x) family which addresses a wide range of 3-phase brushless DC motor control applications includes boards and kits to provide complete evaluation of all functions and peripherals of the particular TLE987x products.
