The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...

Brushless dc (BLDC) motors are widely used in industrial and home applications, such as in HVAC blowers, because of their efficiency and cost advantage. Furthermore, sensorless control of BLDC motors ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

A special type of brushless motor is called a limited-angle torquer (LAT). LATs are constrained to produce torque through a rotation angle of less than 180°. But they are widely used to operate ...

StepSERVO closed loop integrated motors from Applied Motion Products control position, velocity and torque for higher acceleration rates and faster machine cycles in food & beverage applications.

While clutch and gearbox assemblies in washing machines have been replaced with belt-driven induction motors with tachometer feedback, digital-control algorithms will enable direct drive from ...

We manufacture motion control systems built upon step motors, servo motors, BLDC motors, and drives with sophisticated current control algorithms, closed loop operation, integrated controllers, ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.
