Motor Rewinding

Course Overview

The course includes an induction session to welcome and orientate the candidate, and familiarize them with the training centre, health and safety requirements and other important policies and procedures. The training consists of a mix of classroom and workshop sessions and various assessments. Upon successful completion, the candidate will gain the knowledge and understanding to enhance their existing skills about motor winding.

The course is designed for an apprentice or beginner who would like to work as an electrician.

The candidate should have a strong foundation knowledge on electrical systems.

Upon completing the training course, candidates will be awarded a ‘Certificate of Attendance’ from NTI, attested by the Ministry of Manpower.
