Pneumatic motor low engine temperatures. The Pneumatic Quasiturbine engine is a compressed air pistonless rotary engine using a rhomboidal-shaped rotor whose sides are hinged at the vertices. The Quasiturbine has demonstrated as a pneumatic engine using stored compressed air It can also take advantage of the energy amplification possible from using available external heat, such as solar energy. The Quasiturbine rotates from pressure as low as 0.1 atm (1.47psi). Since the Quasiturbine is a pure expansion engine, while the Wankel and most other rotary engines are not, it is well-suited as a compressed fluid engine, air engine or air motor. Armando Regusci's
Electric motor in a single plane is used to make a series stretches and position holds, similar to the way a caterpillar moves. An electrically powered spacecraft propulsion system uses electric motor technology to propel spacecraft in outer space, most systems being based on electrically powering propellant to high speed, with some systems being based on electrodynamic tethers principles of propulsion to the magnetosphere. Electric motor An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and winding currents to generate force in the form of
