Replacing a traditional AC motor with a smaller, more efficient BLDC motor can save energy and cost, but the algorithms required for BLDC control are complex enough that many designers are reluctant to switch. A dedicated IC for BLDC motor control makes the job much easier.
The high level of interconnected technologies in automobiles, the wide variety of new external interfaces, and the linking of personal data with vehicle functions all mean that new security approaches are necessary to protect against hackers. This article outlines the architecture of a trust anchor with the aid of a security processor. Using a trust anchor enables individual operations, larger networks and personal data to be secured against unauthorized access and manipulation.
With more than 200 million motors featuring a power range below 750W, the opportunity for energy savings through the adoption of electronically controlled variable speed solutions is very significant. In fact, 55% of the total electric energy produced today is used to run motors of every size, shape and efficiency.
Motor controls and drives are used to control the speed and torque
characteristics of AC and DC motors, and to restrict inrush currents present the
largest share of the automotive, industrial, and define a rapid growing segment.
Motor controls and drives are an integral part of industrial equipment from
factory machine automation, industrial control, facility management,
packaging equipment to process control.
TI expanded its motor driver portfolio to include the companys first integrated stepper motor pre-driver. The DRV8711 is highly configurable with a best-in-class on-chip micro-stepping indexer, as well as stall detection, and advanced current regulation that easily and efficiently tunes any motor. External MOSFETs control the stepper motor to provide minimum heat dissipation and 20 percent more scalable output current than the nearest competitor allowing designers to customize their design.
Emerson Network Power announced a new 1500 Watt ac-dc power supply that - unlike many other units in the market - does not require any derating at low line and
provides the full power across the input range 90 to 264 Vac.
Smart sweeping robots have become more popular around the world, and ensuring their safety and reliability is an important design consideration. PolySwitch PPTC devices are well-suited to helping protect the equipments motors, batteries and charging ports from damage caused by stalled motors, overcharging and other failures that can be encountered during normal operation. TE Circuit Protection offers appliance manufacturers a broad line of versatile, high-quality protection components and works closely with customers to develop solutions for specific applications.
Isolation is an integral part of ac voltage motor drives. There are several methods of providing electrical isolationprimarily, optocouplers and digital isolators are used. The use of digital isolators provides several benefits as compared to traditional optocouplerssome of which include reduction in cost, component count, and improved reliability. This article will compare methods of isolation in a traditional motor controller design to highlight the benefits of digital isolators.

Important metrics for components going into efficient motor systems include power handling, which should be maximized, and power dissipation and temperature, which should be minimized. This paper will look at various types of motors, and discuss solutions from Bourns that primarily implement current sense resistors used in the motor control circuit.
MEMS oscillators are replacing quartz-based timing devices in electronic motors because they offer better reliability, improved stability, more features, short lead times and lower cost. Industrial motor controlled equipment is often subject to extreme temperatures, high levels of vibration and electromagnetic noise. In the presence of these harsh conditions, oscillators must operate reliably. Read the latest performance data for XOs tested under these conditions.
The COMBO D product line from ITT Cannon offers a wide range of mixed layouts that could handle different size 8 contacts for individual customized solutions. This connector system is ideal for applications that require optimization of space while improving overall shielding. Thus the over leakage of EMI/RFI gets eliminated.
Automotive Adaptive Front Lighting Systems (AFS) use stepper motors to adjust the headlamp position vertically and horizontally to enhance road safety and driver comfort. This article discusses the challenges facing AFS designers, and details how designers can employ the NCV70522 stepper motor driver from ON Semiconductor to ensure correct behavior of the motor under normal operating conditions, and to implement robust stall detection for consistent headlamp positioning and self-adjustment for maintaining accuracy.
This article shows how to use a microcontroller of the STM32F30x family to reduce considerably the number of external components required by field oriented control of a three phases motor. The compact design achieved in this way allows to save the cost of the components, the PCB space required and simplify the complexity of the schematic, gaining the advantage of robustness of security features.
The inclination in automotive industry is to shift to electric motor technology based systems from mechanically actuated automotive systems, to reap the benefits of cost-effective designs, low-noise, high-accuracy and power efficient systems. This has led to an exponential rise in the number of microcontrollers in the automobiles.
Microsemi offers motor control solutions that can deliver precise control of multi-axis motors. Sensor-less field oriented control (FOC) of brushless DC motors (BLDC) and permanent magnet synchronous motor (PMSM) requires complex algorithms to be developed. While microcontrollers and DSPs have traditionally been used for developing these algorithms, these devices cannot keep up with increasing demands of multi-axis motor control requirements. Building these complex algorithms in hardware-based FPGA designs is known to give higher performance and better reliability.
Small motors operating at less than 300 W are used in a wide variety of applications including automotive systems, printers, copiers, paper handlers, toys, factory automation, test equipment, robotics, aerospace and military, and many others. The most popular small motors types are DC, brushless DC and stepper motors. The quantity of motors produced is roughly inversely proportional to the power level. Small motors are produced in much higher quantities than larger motors.
Due to high-volume production techniques, Thyristors are now priced so that almost any electrical product can benefit from electronic control. A look at the fundamentals of SCR and Triac phase controls shows how this is possible.
Today, with new technologies and processes, magnetic sensor manufacturers can achieve high sensitivity and magnetic stability without using chopper stabilization. This translates into improved sensor performance in terms of faster response time and better repeatability from the sensor.
