Often, BLDC motors are controlled using the 120° commutation logic, which naturally approximates the maximum torque per ampere (MTPA) operation. However, in some applications, the 180° commutation is ...

Abstract: In this article, through a newly proposed rotor regionalization design method, a direct-drive hub permanent magnet (DD-HPM) motor is designed for electric vehicles. The key of the research ...

We are renowned for our quality of teaching and have been awarded the highest grade in every national assessment. Ranked 3rd in the UK in the Complete University Guide (2023/24) and 15th in the world ...

To select the right stepper motor, it’s critical that its pull-out and pull-in torque curves are considered. Understanding these attributes, as well as how to measure them, is a crucial aspect for the ...

This project also contains the model of a detailed permanent magnet synchronous motor (PMSM) and controller. It captures the detailed behaviors of the AC motor drive unit and can estimate the ...

Walking experiments were conducted with multiple angle-based desired torque curves. The observed lowest torque tracking ... of an off-board real-time control module and geared electric motor, a ...
