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 ...

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 ...

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 ...

Electric motors, which convert electrical energy into mechanical energy, play an essential role in a variety of industrial and robotics applications. Given that electric motors account for ...

Most known for their versatility, electric motors have revolutionised the way we view the core definition of power, qualifying it as effective energy expenditure concerning work done over time. Among ...

High-performance motors need a control mechanism that ensures enhanced smoothness, reliability, and efficiency. One of the most apt examples of such an application is the motor used in ...

A new sensor on a pedal-electric bike (pedelec) tracks torque from pedaling and applies supplemental motor power on the fly. A pedal-electric (pedelec) bike uses a special sensor to synchronize power ...

Sensorless motor control has primarily been applied to applications where the majority of the operating time is at higher electrical frequencies (mechanical speeds). This is due primarily to the fact ...

Torque requirements for motor control circuit device terminals shall be a minimum of _____ lb-in. (unless otherwise identified) for screw-type pressure terminals used for 14 AWG and smaller copper ...

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 ...
