In this paper, a novel method based on a combination of Extended Kalman Filter (EKF) with Self-adaptive Differential Evolution (SaDE) algorithm to estimate rotor position, speed and machine states for a Permanent Magnet Synchronous Motor (PMSM) is proposed. In the proposed method, as a first step SaDE algorithm is used to tune the noise covariance matrices of state noise and measurement noise i...

Aiming at the shortcomings of complex mechanical transmission structure and low efficiency existing belt conveyor driven by asynchronous motor, this paper focuses on investigation a new type low-speed high-torque-density direct-drive permanent magnet synchronous motor (LHDPMSM) for driving conveyor. The proposed LHDPMSM utilizes external rotor to achieve goal fully direct drive First, topology ...

Axial flux electric motors have received a lot of attention in recent years due to successful implementations industrial or traction applications. Particularly, axial permanent magnet synchronous (AFPMSM) can be an attractive choice case high torque-density requirements when the drive environment (packaging) is geometrically limited disc-shaped motor. However, compared radial motors, machine mo...
