Three-Phase Add-On Motors Program With Options
All of the rotating electrical machines and accessories required for a basic Electrical Power course are contained in the
Mini-Motors Laboratory. The equipment illustrated is the basic package,to which compatible motors, controllers, and accessories may be added.Bedplate:-Holds motors and generators securely during tests. Includes quick-connect coupling and shaft guards. DC Motor/Generator:- May be used as either motor or genera- tor; series, shunt, or compound. Series Field Rheostat:-Changes the degree of compounding of a DC generator
Dynamometer:- Measures torque in ounce-force inches in either direction. May also be used as DC motor or generator.
Synchronous :-Motor/Alternator Runs as a synchronous motor or oper- ates as a three-phase alternator when driven by AC or DC motor.
Multi-Function Machine:- Runs as a split-phase; a capacitor start; a permanent-capacitor; or a two-capaci-tor motor.
Resistance Load:- Applies resistive load to generators and alternators.
Resistance/Reactance Load:- Applies unity, lagging, or leading power factor load.
Measures speeds between 100 and 12,000 RPM
Digital Optical Tachometer Measures speeds between 0 and 10,000 RPM with accuracy of 0.25% of actual speed.
Power and Metering
To satisfactorily perform the required experiments, the following power should be available:
• Fixed 120V AC 1 2-wire 10A
• Fixed 208/120V AC 3 4-wire, 10A
• Variable 0-240/140V AC 3 4-wire, 9A
• Variable 0-150V DC, 1.0A, isolated,1% RMS
• Variable 0-125V DC, 5.0A, isolated, 1% RM
The following meters should also be avail- able:
• DC Voltmeter; 0-75/150V (2)
• DC Ammeter; 0-0.5/1.0/2.5/5.0A (2)
• AC Voltmeter; 0-150/300V
• AC Ammeter; 0-0.5/2/4/8A (2)
• AC Wattmeter; 0-150/300/600/1200W (2)
