Maxwell’s Bridge is used for the measurement of inductance in terms of comparison with a standard variable capacitance using the following equation. This trainer has capability to measure inductance in the range of 1mH to 1H
Lx = C1 R1 R2

Lx is unknown inductance, R1& R2 non-inductive resistance and a standard capacitor-C1. In this bridge we are having three sections. A built in oscillator section with a frequency. A bridge section with four arms. Arm AC consists of unknown inductance (Lx). Arm AD consists of Variable non-inductive resistance R1. Arm CB consists of non-inductive resistance R2 with multiple selection ranges. Arm BD consists of parallel network of fixed & Resistance (R3) with multiple selection ranges. The balance of bridge can be observed using a built-in audio amplifier with loudspeaker arrangement. This acts as a null detector.

2. Ammeters – analog / digital
3. Watt-meters – analog / digital
4. Phase sequence indicators
5. Tacho meters – contact type and photo reflective type

This DC motor is integral, internally mounted cooling fan on the shaft. When the motor is running at rated speed the, fan provides the necessary cooling to give the assigned rating. When motors are required to start from zero speed and smoothly accelerate to the rated speed, these motors can be selected. If motors are to run below rated speed for long duration, either they have to be de-rated or can be forced cooled. The DC Generators are normally continuously rated and have to run at rated speeds only.

This requires DC rectifier source for its operation. The DC source to this is provided through a 3-4 point DC starter unit. Using this, several experiments on DC motor can be conducted. Depending on the experiment, you need appropriate meters, rheostats, switchgear are required. These motors are screen protected, with IP21/IP22 enclosures.
