With this simple electric motor model students can investigate the relationship between voltage supplied to rotor and polarity / position of magnets.
On applying 6V DC to 4mm sockets, the rotor will begin to rotate across its vertical axis.
Designed to demonstrate to implement and applications of electrical, electronic devices and simple circuits. These modules are fitted with 4 mm sockets.
Components are directly mounted on printed PCB with diagram.Various modules are available as following Resistor
LDR
LED
Push Switch
Motor
Reed Relay
Reed Switch
Relay Nand Gate
Buzzer
Thermistor
Lamp Holder
Single Pole Double Throw Switch
Electromagnet
Power Transistor
Enables students to investigate nature and properties of electricity by using simple circuits which are easily constructed on a base board.
The connector system uses P.C.B. strips with cut-out sections whose ends can easily be inserted in spring terminals, ensuring low contact resistance and ease of connection.

This apparatus is an effective demonstration of how the earth wire and fuse act together to protect both the user and the appliance.
When the appliance is connected correctly and the LEDs in the appliance will illuminate to show the appliance is working.
A fault is then demonstrated by swapping the live wire from inside the appliance to the case to show either the fuse melts (protecting the user and appliance) or in the case of no earth wire, the LEDs illuminate to indicate the passage of current through the person to ground.
The fuse is easily visible and can be seen to ‘blow’ when a fault occurs.The unit is supplied with 10 m of fuse wire and full instructions.
A 12 V DC power supply is required.
Connections are made via 4 mm shrouded sockets.
The dynamo model is mounted on a base with a driving wheel.
Output is through 4 mm sockets and a low voltage bulb is also provided as a simple output indicator.
Wound on rectangular bobbin, for use with 220 – 240 V AC mains with detachable mains connector with moulded plug, A 4 mm socket is provided for earthing.
