When the heart weakens and fails\u00a0to pump blood at physiological rates commensurate with the requirements of tissues, two main alternatives are cardiac transplant and ventricular assist devices (VADs). This article presents the design strategy for development of a customized VAD electromagnetic actuator. Electromagnetic actuator is a brushless direct current motor customized to drive the\u00a0pump impeller by permanent magnets located in rotor\u2013stator coupling. In this case, ceramic pivot bearings support the\u00a0VAD impeller. Electronic circuitry controls rotation switching current in stator coils. The proposed methodology consisted of analytical numerical design, tridimensional computational modeling, numerical simulations using Maxwell software, actuator prototyping, and validation in\u00a0the\u00a0dynamometer. The axial flow actuator was chosen by its size and high power density compared to the\u00a0radial flow type. First step consisted of estimating the required torque to drive the\u00a0pump. Torque was estimated at 2100\u00a0rpm and mean current of 0.5\u00a0A. Numerical analysis using finite element method mapped vectors and fields to build stator coils and actuator assemblage. After tests in the dynamometer, experimental results were\u00a0compared with numerical simulation and validated the proposed model. In conclusion, the proposed methodology for designing of VAD electromechanical actuator was considered satisfactory in terms of data consistency, feasibility, and reliability.<\/jats:p>","DOI":"10.1111\/aor.13556","type":"journal-article","created":{"date-parts":[[2019,8,22]],"date-time":"2019-08-22T19:09:39Z","timestamp":1566500979000},"page":"797-802","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A
