Stepper motors are useful for relatively low-speed, intermediate-torque drive and positioning applications, particularly where accurate sub-revolution rotor position control is necessary. Motors of ...

Brushless DC (BLDC) motors are standard fare in low-precision, speedy RC applications. The control schemes needed to run them slowly or precisely go deep into motor theory and might put these motors ...

Motor control centers (MCCs) were first introduced in 1937 as a way to conserve wall and/or floor space in industrial facilities. Before 1960, wall-mounted motor starters were used even if only a few ...

Humans have a complex body with more degrees of freedom than needed to perform any particular task. Such redundancy affords flexible and adaptable motor behavior, provided that all degrees of freedom ...

Read part 1 of this series on construction and operating principles here. Having understood the construction and basic operating principle of BLDC motor in the first part of this article, it becomes ...

Motors account for at least half of the energy consumed in the U.S. Selecting the right control method for an application lets the motor run most efficiently while maximizing torque and overall ...

Over three decades ago, real-time software was predominantly written in assembly language or a combination of assembly and the C programming language. Even today, certain digital signal processing ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...

As previously mentioned, the feedback sensors include position sensors to track the rotor’s location, current sensors to measure the motor phase currents, voltage sensors to monitor the DC bus voltage ...

Owing to advances in neuroimaging techniques coupled with clinical work, considerable progress has been made in understanding the functional rules of brain organization. Two fundamental principles ...

As with internal-combustion vehicles, the advantages of all-wheel drive for electric vehicles have been obvious from the start as has been the potential to provide multiple motors, ideally one for ...
