Brushed DC motor
From home and garden, to power tools, to Automotive: 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
Example application for brushed DC motor control and drives (highly integrated)
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)
How Infineon can support you
Infineon covers a wide range of brushed DC motor control applications, including sunroof, power window lift, and electrical pumps and fans, with a complete system-on-chip solution known as Embedded Power ICs. The TLE984x and TLE986x product families, parts of the Embedded Power ICs range, are designed to provide reliable, energy efficient, size and weight optimized solutions.
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. TLE984x, TLE985x and TLE986x product families which are designed to address brushed DC motor aplications includes boards and kits to evaluate particular TLE984x, TLE985x and TLE986x products.
