Motor control

The most complex and challenging technical environments in the world are found in heavy industry applications, which require reliable, robust, and compact drives.

By varying the frequency and voltage of the motor signal, general-purpose drives enable the speed of a motor to be controlled. General-purpose drives are used in applications such as pumps and fans, process automation, or cranes in the power range from a few hundred watts to the megawatt range.

Our product offering combines excellent performance and reliability, offers a competitive price/performance ratio, and ensures the safety of your motor system. We offer you a broad portfolio of efficient semiconductors optimized for the motor inverter. 

It does not matter if you choose a 2-level topology, multi-level topology, or a cascaded H-bridge solution, Infineon offers a wide range of suitable solutions for these applications.

A servo drive is used to power electric servomechanisms by receiving a command signal from a control system, amplifying it, and transmitting the electric current to a servo motor. It allows producing motion that is proportional to the command signal. A servo drive monitors the mechanism's feedback signal. It also continually adjusts in case of deviation from the expected behavior. With this feedback, the commanded motion's accuracy can be ensured, and unwanted motion can be detected. A unique characteristic of the servo motor is that it consumes power while rotating to the desired position and then rests upon arrival.

Infineon offers you a broad portfolio of semiconductors for your servo motor design ranging from several hundred watts to several hundred-kilo watts applications. Our products are specially designed for use in Robotics, Material handling or machine tools, and many more to reach high reliability, longer lifecycle, high position accuracy, and fast response without overshoot.

Whatever you touch in a car, there is an electric motor close by. Brushed DC motors are easy to control and often serve as actuators with an overall short operating time. Torque control down to zero speed is easy to achieve.

Brushless DC (BLDC) motors have less wear but need a complex control algorithm and, therefore, higher computing power than a DC motor drive. BLDC motors are most suitable for applications demanding long-term continuous duty like fuel pumps.

48 V battery systems offer significant current reduction and weight reduction for the wiring harness resulting in lower fuel consumption. While the selection of 48 V micro-hybrid components is currently limited, Infineon provides cost-effective and high-performance electrification solutions for applications in both entry-level and upper market segments. 

The traction inverter is an essential component for electric vehicle (EV) drivetrains, as it controls the motor and determines driving behavior. It minimizes switching losses, maximizes thermal efficiency, and enables regenerative braking to recharge the battery. Infineon provides a complete system solution for traction inverter design to achieve high efficiency, optimized performance, and fast time to market.
