Wire up the following:
CAUTION: Be sure when wiring the
motors and generators that the power is off, and that you don't have
any part of your body touching the metal case of the motor or the
trainer enclosure. (These cases are grounded and will complete
the circuit if you are also touching a hot wire, and the switch should
fail or accidentally get turned on.)
- ID29-20A, 7 points--A three phase motor in the Y
configuration. Then, reverse the direction of rotation. Instructor's
initials _______
- ID29-20D, 7 points--A capacitor-start motor. Instructor's initials _______
- ID29-20B, 7 points--A DC motor in the shunt configuration,
with the pot controlling the field current. (Use the F field winding.) Instructor's initials _______
- ID29-20C, 7 points--A DC motor in the series configuration.
Don't let the motor explode! Be sure to have drag supplied by a prony
brake. (Use the S winding.) Instructor's initials _______
- ID29-20A, 15 points--A DC generator in both shunt and series configurations. Use the light board as a load. Instructor's initials _______
- ID29-20D, 5 points--Two transformers in series. Instructor's initials _______
- ID29-20E, 7 points--Two transformers in parallel. Use a
voltmeter to check for zero volts before connecting the last wire. Be
aware of whether the transformer is getting warm, but don't touch the
bare windings (even though they're insulated with enamel). Instructor's initials _______
