Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

The increasing use of high-current brushless DC 3-phase motors is undoubtedly imposing stringent requirements on drive electronics from both function and safety aspects. Higher operating voltages and ...

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

Overload devices protect motors, motor control equipment, and motor branch-circuit conductors against excessive heating due to motor overloads and failure to start, but not against overcurrent (e.g., ...

Having reviewed the basics of BLDC motor control in Part 1, the design effort canbegin.. The first quest is to select a microcontroller. Looking in themarketplace there are several microcontrollers ...

A typical low-voltage variable-frequency drive. Industrial facilities commonly use variable-frequency drives (VFDs) to control the speed at which alternating current motors operate. Let’s examine a ...

Power Integrations’ updated Motor-Expert Suite now features three-phase field-oriented control (FOC) software, including a reconstruction algorithm that uses the phase-shifted trigonometric ...
