Dc Motor Coupled 1 Ph. Synchronous Motor Trainer (Model : XPO-EMT/DC+1 PH. SYNC)

Rated 0 out of 5

This teaching setup is designed for students learning about electrical engineering. It features easy and safe wiring using specific cords and sockets. Machines are mounted on sturdy frames for easy interchangeability, and gear coupling allows for hassle-free connections. The machines operate at levels up to 300W and speeds of 1500 RPM, prioritizing student safety. A special DC Integrated machine acts as a Dynamometer, loading both motors and generators and measuring shaft power. The setup includes materials like student workbooks and instructor guides for effective learning.

SALIENT FEATURES

Facilitates easy and safe wiring by students due to use of 4mm sturdy shrouded banana patch cords and shrouded socket arrangements.
All machines are mounted on finely painted sturdy base frame with easy machine interchangeability Use of gear coupling facilitates screwless coupling.
With due emphasis on student safety machines operate up to 300W power levels and up to 1500 RPM, without compromising didactic use Able to draw all graphs.
Trunnion mounted DC Integrated machine is used as Dynamometer for loading other machines (Motors / generators both); unlike magnetic powder brake or eddy current brake which can load only coupled Motors and not generators, with facility to measure shaft power using electronic torque / speed measurement
Set of Students Workbook & Instructors Guide.
