71-3-L004-A : Motor, 3 phase, 44W, 4 pole, 41.5Vac, 50Hz, SCIM

Price $605 + Freight & handling + GST

This is a 3ph, 44W, 4 pole, 41.5 Vac, Delta connected(Δ), 50Hz, Squirrel Cage Induction Motor (SCIM)

The motor has six(6) leads terminated at the terminal box with 4mm diam. sockets enabling the motor to be externally connected for Star/Delta (Y/Δ) starting.

HANDS-ON
Concept
The motors designed low output of 44W enables the student to grip the shaft mounted metal coupling in their hand to stall (Locked-Rotor) the motor. This enables the student to physically feel the difference in torque between the Star(Y) and the delta(Δ) connection as predicted in the theory. i.e. T(star)= 1/3 T(d.o.l.(Δ))

In combination with the following auxiliary equipment all the various 3ph SCIM reduced voltage starting methods can be demonstrated
