Universal Motor.
Universal motors- as the name suggests are universal because they can
run on AC Supply as well as DC Supply, they belong to the family of
Single phase motors with the difference that they have wound rotor,
commutator & brush as used in dc motors. These motors are
for intermittent duty cycles as their RPM is very high and find
application in domestic mixer grinders & home appliances, industrial
use is switch yards in power sub stations for spring charging of
circuit breakers.This Model is the industrial/educational model suitable
for demonstrating to students the complete know of the basics,
components, starting methods, speed-torque, wear & tear &
maintenance of these motors packaged in small rating. Students can make
connections of their own with the help of the terminations provided for
study of features viz Starting methods, speed-torque, effect of reduced
voltage, Blocked rotor test. Technical Specs :
Power ratings available : 350W / 750W
Voltage Input: 230V AC 50hz or 230 DC
