Automotive Electro Trainer provides a "hands-on" working knowledge of voltage, current, and resistance with series and parallel circuits. Over 250 of these currently used to train. Automotive Electro Trainer kit allows students to gain a foundation in the principles of electricity and electronics. Graphic symbols are screened into each component's acyrlic background. This helps students to understand circuit reading and wiring diagrams. It provides a "hands on" working knowledge of voltage, current, and resistance with series and parallel circuits.

The planet gears are mounted on a planet carrier and engage positively in an internally toothed ring gear. Torque and power are distributed among several planet gears. The planetary gear is a special type of gear drive, in which the multiple planet gears revolve around a centrally arranged sun gear. Sun gear, planet carrier and ring gear may either be driving, driven or fixed. The trainer consists of two planet gear sets, each with three planet gears. The ring gear of the first stage is coupled to the planet carrier of the second stage. By fixing individual gears, it is possible to configure a total of four different transmission ratios. Planetary gears are used in automotive construction and shipbuilding, as well as for stationary use in turbines and general mechanical engineering. Unit allows the investigation of the dynamic behaviour of a two-stage planetary gear. The gear is accelerated via a cable drum and a variable set of weights. The set of weights is raised via a crank.
