This device is a low voltage triple half-bridge BLDC motor driver with a current rating of up to 1.3Arms, the device integrates control logic, drive FETs and protection into a single IC. Below are some examples of a couple of devices which suit some of the more common applications. The STSPIN product family includes various devices, each are tailored to the specific needs of different motor types. The family also includes variants which have an embedded STM32 MCU offering a fully integrated System-In-Package solution. These products integrate the power electronics, control electronics, and protection features required for driving and controlling motors.

STMicroelectronics motor control and drive solutions are suitable for all of these common motor types and more besides.įirstly, we will look at the STSPIN product family, this is a range of integrated motor drivers that are designed to drive and control 3-phase brushless DC (BLDC) motors, stepper motors, and single-phase DC motors. Their structure is similar to that of stepper motors, but they have fewer magnetic poles. Switched reluctance motors are more commonly used in traction, industrial pumps and domestic appliances. Stepper motors are designed to make small incremental movements/steps rather than just rotation like a traditional motor, they are widely used where precision position control is required such as in computer drives, security and industrial automation sectors. Typical applications include industrial pumps and conveyer belt systems. Three-phase induction motors (ACIM) are brushless motors commonly used in industrial drives, these motors feature self-starting, reliable and economical operation. These versatile motors are used in applications that require high torque and high-speed operation such as robotics & power tools. Josh Barton, Field Applications Engineer at Anglia gives an overview of the STSPIN and STDRIVE product families, their features and advantages, and how they can be used effectively to drive and control electric motors.įirstly, let’s look at some of the common motor types in use today and their specific strengths for different applications.ĭC brush are the most common motor type however, these are now being replaced in many applications by Brushless DC motors (BLDC) due to advantages such as higher efficiency, quieter operation and increased reliability. The STMicroelectronics STSPIN and STDRIVE product families have been designed with the needs of modern industrial control applications in mind, such as industry 4.0, and are able to intelligently drive and control electric motors with high efficiency and precision.
One of their key areas of expertise is the design and manufacture of motor control ICs. STMicroelectronics is a leading supplier of semiconductor solutions for various industries, including eMobility, industrial, and personal electronics. These motors require sophisticated electronic control systems that need to be highly integrated and cost effective whilst at the same time provide the necessary current and voltages and achieve precise control and efficient operation. This has helped to speed up the adoption of the intelligent manufacturing equipment used in Industry 4.0. The proliferation of electric motors in industrial and consumer applications has revolutionized the way we operate machines and equipment. Intelligent, Efficient and Precise Motor Control
