Brushed DC motor
From home & garden, to power tools, to fans: no matter your brushed DC motor application or budget, find the ideal solution in Infineon's broad semiconductor portfolio. You can achieve energy and cost efficiency by selecting one of our designated solutions for the three main types of brushed DC motors. All in proven Infineon quality you can depend on. Find what's best for your application: look through our diverse range of suitable high-quality products. See additional motor control applications here in battery powered applications and home and building.
There are three main types of brushed DC motors: series wound (uni-directional), shunt wound (bi-directional by changing connections) and permanent magnet (bi-directional by reversing current). Powering a set of windings generates a magnetic field in the rotor. The opposing magnetic fields (N-N and S-S) push away from one another creating rotation until the fields align (NS – NS).
Example application for brushed DC motor control and drives
Key characteristics brushed DC motor
- Easy to control: torque is proportional to current – speed is proportional to voltage
- Moderate efficiency
- Variable speed: fewer external components required than induction or brushless DC motors
- Maintenance necessary as brushes wear out
- Louder than induction motors (EMI and audible)
XMC1000 and XMC4400 motor control application kits
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 witha 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.
300W motor control application kit and the eval 5kW TO-Leadless evaluation board
The 300W Motor Control Application Kit is made to drive pedelecs, power tools or other low-voltage drives. The kit contains a driver and a graphical user interface (GUI) in order to make it as simple as possible to run a brushless DC motor, for example. 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.
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.
