1 SOLAR MOTOR - LOW INERTIA type motor utilising precious metal brushes. Operating range 1.5-9V. Starting current 10mA approx. Size: 32mm dia. x 19.5mm length. Shaft 2mm Dia. Cat No. Description Price Per HSE-350-100 Solar Motor 1.64 ea. 2 SOLAR MOTOR MOUNTED This is a small, low consumption electric motor, mounted on a base with 4mm sockets. Specially designed to run directly from the output of a solar cell and to illustrate the direct conversion of light energy to electrical and hence to mechanical. Cat No. Description Price Per HSE-130-100 Solar Motor Mounted 10.18 ea. 3 SOLAR CELL MOUNTED For use with a solar motor to demonstrate the production of electrical energy directly from light energy. The apparatus comprises a selenium photo-voltaic cell, mounted on a metal stand. Cat No. Description Price Per HSE-140-100 Solar Cell Mounted 18.75 ea. 4 LASCELLS SOLAR CELL ARRAY This unit measures 200 × 70 × 60mm and houses four solar cells, each 50 × 30mm. The cells are connected to 4mm sockets along either side of the base so that they may be connected together in any combination. Two screw terminals are provided for connecting load resistors etc. Cat No. Description Price Per HSE-145-100 Solar Cell Array 64.68 ea. 5 MINI WIND TURBINE This mini-turbine can be used to introduce basic principles of a wind turbine. It consists of a small electric motor attached to a propeller and connected to a pair of terminal posts. To demonstrate how the turbine can generate an electrical current, it can be connected to an LED or electric motor. To measure the output, it can be connected to a voltmeter or digital multimeter – the faster the turbine turns, the higher the voltage reading. The mini-turbine can be used to carry out simple investigations into the effects of different wind speeds and angles on output, using a desk fan, for example. The wind speed can be varied by using the settings on the fan. The mini-turbine can be held in the hand or, for a more quantitative approach, held in a clamp stand, which allows distances and angles to be measured more accurately. Cat No. Description Price Per EWE-730-100 Mini Wind Turbine 14.34 ea. 6 WIND TURBINE KIT To measure the power of wind. Contains all that is needed to convert wind energy into electricity. By increasing the number or angle of turbine blades, effects can be measured. The kit can be used indoors using a desk fan. Cat No. Description Price Per EWE-750-100 Wind Turbine Kit 165.75 ea. 7 FAN Desk fan, for providing a convenient source of air-flow for wind- energy investigations. Also useful for keeping cool in hot weather! 30cm diameter. 230 Volts a.c. Cat No. Description Price Per FAN-100-100 Fan 19.57 ea.
