The Hampden Model DC-MS-100 is designed for use with the Hampden Series 100 DC motors to study the operation of 3 and 4 point manual motor starters.
The Hampden Model RLC-100 is a variable resistance and reactance (either inductive or capacitive) unit that may be used to apply a single-phase or a three-phase load.
To utilize the SYN-100, the outputs of two three-phase alternators must be patched into the unit. Alternator #1 should be connected to the upper row of jacks and alternator #2 connected to the lower set.
The Hampden Model MS-100-3A is a three-phase starter which uses a 3 pole contactor to apply power to the stator of an induction motor, such as the Hampden Model IM-100 Squirrel Cage Induction Motor or the Hampden Model WRM-100-3A Wound Rotor Motor.
The Hampden Model CL-100A is a variable capacitance unit used to apply a capacitive load for loading alternators.
The Hampden Model VIL-100 consists of a freely rotating 5/8" diameter shaft held by adjustable shaft supports and collars. This mounting scheme allows for exact alignment with the motor under test and minimal frictional losses.
The Hampden Model VRL-100B is a variable resistance unit used to apply a resistive load to generators or alternators.
The WRSC-100 is used to vary the speed of the Hampden Model WRM-100-3A Wound Rotor Motor.
The Hampden Model H-REM-LC-D Load Cell is designed to be used with any standard Hampden dynamometer, replacing the circular scale. The signal conditioner measures and displays torque on a digital read-out. Two separate amplifiers are used to permit torque measurements in either English units (lb-ft) or SI units (N-m). Separate analog output (0-5V DC) is available via Hampden HR-1S receptacles on the rear of the unit.
The Hampden Model DB-100 Dynamic Braking Demonstrator consists of a 25 ohm, 25 watt resistor wired to a three position function switch.
In certain applications involving DC motors, it is sometimes desirable to add resistance to the armature circuit to limit the amount of current in the circuit when the motor is started. Generally, a rheostat is chosen to limit the armature current in the circuit to approximately 1.25 to twice the rated amperes, at the moment the machine is started. Series resistance can also be employed as a form of limited speed control on various motors, such as DC series or shunt motors.
The Hampden Model DC-CEMF-100 Starter is basically a controller using a form of current limit acceleration known as counter electromotive force (CEMF) acceleration.
The Hampden Model ACSS-100 is intended for use with the SM-100-3 Synchronous Machine. It provides the AC and DC excitation and the DC switching required to start the SM-100-3.
In certain applications involving polyphase induction motors, it is sometimes desirable to have available a means of braking the motors speed (e.g., an overhauling load). Unlike the DC motor in which the armature is disconnected from the line and connected across a resistor as a generator (as with the Hampden Model DB-100 Dynamic Braking Demonstrator), there is no way to disconnect the primary armature of an induction motor and still maintain excitation of the rotor secondary in the same manner. Braking can still be accomplished, however, if the primary excitation is removed and if the stator is excited with direct current instead.
The Hampden Model PB-100A is a mechanical loading device used to load motors, consisting of a shaft with supports, 6" diameter pulley, belt, lever arm, counter balance weight, adjusting knob, and spring scale.
The Hampden Model SFR-100 consists of a chassis mounted, ten ohm, fifty watt rheostat whose terminals are brought off a DC motor. With the rheostat set for maximum resistance, a portion of the series field current is diverted through the rheostat, thereby weakening the series field strength. As the resistance of the SFR-100 is decreased, a greater portion of the series field current is diverted, resulting in a proportionately weaker series field strength.

The Hampden Model PSI-100 is supplied in a three-phase configuration with two pilot lights and a two position switch located on the panel face. In addition, four binding posts (three-phase, one neutral) are supplied for the various connections required.
The Hampden Model IL-100A is a variable inductance unit used to apply an inductive load. One unit may be used in single-phase applications, or a bank of three units may be combined into wye or delta configurations for three-phase applications.
The Hampden Model RL-100A is a variable resistance unit used to apply a resistive load to generators or alternators.
