In a speed controller, the motor’s speed (or velocity) is being controlled. There is an element that detects speed, whether it be a tachometer or some sort of encoder. This monitoring element provides ...

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 ...

By maxon The new 22mm diameter BLDC motor in maxon’s ECX PRIME series increases nominal torque to 69.1mNm with high-speed ...

STMicroelectronics has released the STM32 ZeST (Zero Speed Full Torque) software algorithm, designed to run on STM32 microcontrollers, that lets sensorless motor drives produce full torque at zero ...

To reap all the benefits that an electric motor drive can offer, choose one that's a perfect match for your application A speed control enables the motor to achieve maximum efficiency during all ...

In an RL-based control system, the turbine (or wind farm) controller is realized as an agent that observes the state of the ...

The most common arrangement, which is used with only minor variations from small drives of say 0.5 kW up to the largest industrial drives of several megawatts, is the so-called two-loop control. This ...

Choosing the right motor and VFD type depends on a variety of factors, however, it is necessary to first look at how the characteristics of a motor change when the speed is reduced —Sponsored article ...
