Development and Control of PMSM Drive With Improved Performance Over Wide Speed and Load Ranges

IEEE Access
Generally, an inverter fed motor drive is often operated under low speed and/or light loads. Hence, except for good driving characteristics, having evenly high efficiencies over wide load range is also critical for a high-performance motor drive.

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

FEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Performance Improvement of a Single Phase Induction Motor Fed by Nonsinusoidal Voltages [PDF]

Engineering and Technology Journal, 2008
The distorted voltage waveforms, which have, more or less, a high harmoniccontent, have negative impact on the long-term performance of the motor, as theycause nonsinusoidal currents in the stator and the rotor, and consequently additionallosses and ...

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...
