A Range of Motor Control Devices for Every Application

Incredibly, one of our DC motor control devices has been in production for more than 40 years, coming to market on the wave of the emerging home video market and VHS recorders. Since then, motor technology and the semiconductors used to control them has changed significantly. A push for higher efficiency coupled with deeply integrated system-on-chip (SoC) solutions means that brushless DC motors (BLDC) can deliver more performance in a smaller package. This has enabled applications such as drones, and forms the basis of maintenance-free fan technology. Stepper motors too provide precision control and are the control choice for the growing 3D printer industry.

Our recent webinar looks at the wide range of motor options on the market and highlights how Toshiba’s portfolio of motor control technology has been tuned and adapted to meet the diverse collection of demands and requirements that have evolved over recent decades. For example, Intelligent Phase Control ensures optimal, energy-efficient commutation for BLDC applications, while Automatic Gain Control (AGC) optimizes torque while minimizing power consumption in stepper motor applications. For traditional DC motors, compact H-bridges utilize the latest BiCD process technology to implement low RDS(on) switches, delivering up to 3.5 A and handling up to 50 V.

However, once embedded in our selected industry segment, many of us never really have to contend with convolution, Laplace transforms, or the details of Fourier since we end up developing applications that use this mathematics, rather creating the algorithms themselves.
Making Field-Oriented Control of motors simple
The move from mechanical to electronically controlled commutation of motors, coupled with new battery technologies, has opened up a wide range of new applications. Microcontrollers are often the best choice for implementing the motor control since their features are also required to implement other features of the end application. This is made especially challenging when considering the hard-real-time demands of electronically commutating a motor.
How do hardware accelerators simplify motor control applications?
Hardware accelerators have been an essential feature of microprocessors for decades, providing performance for features that the processor is unable to execute efficiently itself. Many times, this circuitry has been dedicated to performing floating point calculations or complex mathematics to bridge a performance gap of the processor’s instruction set. The advantage they often bring is determinism to calculations that, without them, would complete in varying time periods. In the world of control systems, such as motor control, this reliable determinism is highly beneficial.

How to control latching relays in smart power meters - an alternative use for brush motor driver ICs
Magnetic latching relays are key components in today’s smart power meters, where they are used to facilitate the remote disconnection and reconnection of power to the consumer premises. A key benefit of such relays is their low power consumption as they maintain last contact position after the control power has been removed. Turning the relay on and off simply requires a momentary application of a trigger pulse current to the relay coil. A pulse in one direction will set the relay to the first position, and a pulse in the other direction to the second position.
Implementing More Effective Motor Drives
In order to respond to growing pressures to curb energy consumption, greater prevalence of variable-speed motors is being witnessed. Such motors are being incorporated into heating ventilation and air conditioning (HVAC) equipment, domestic appliances (dish washers, refrigerators, washing machines, etc.), light industrial drives and suchlike. These motors, in turn, call for inverter drives to propel them. A key concern, however, when specifying inverter drives for these types of applications is the associated cost.
HV-IPDs Will Play Integral Role in Driving Further Energy Improvements in Domestic Appliances
Consumer attitudes are changing and the energy ratings of domestic appliances are becoming an increasingly important aspect of modern purchasing decisions - whereas previously it would have come a long way down the list (somewhere below, features, price, aesthetics, etc.). For such items to attain high scores in relation to their energy rating, variable speed operation is necessary (in contrast to the less sophisticated ‘all or nothing’ approach of the past). This allows great efficiency levels to be realised, with a number of different benefits subsequently being derived.
In search of a quieter life - combatting noise and vibration via innovations in motor control
To meet the pressing need for elevated levels of energy efficiency, the conventional direct current (DC) motors incorporated into electric fans, domestic appliances, air conditioning systems, office equipment and such like, have over time been replaced by more sophisticated three-phase brushless DC (BLDC) motors. This has enabled compliance with the stringent international environmental guidelines that have now emerged, as well as helping to reduce the size of utility bills.
Satisfying Automobile Industry’s Demands for More Effective Motor Control Solutions
The prevalence of electric motors in automotive designs is increasing considerably, as a substantial proportion of modern vehicles’ functionality is migrated away from traditional mechanical implementations towards modern streamlined electronic implementations - in order to reduce weight and thereby improve fuel economy. Among the areas where electric motors are now seeing widespread deployment are in fuel/oil/water pumps, exhaust gas recirculation systems and electric power steering systems.
