2. AC motor - Wikipedia

   en.wikipedia.org/wiki/AC_motor

   The micro speed unit combines two motors and an intermediate gear reducer. These are used for applications where extreme mechanical positioning accuracy and high cycling capability are needed. The micro speed unit combines a “main” conical rotor brake motor for rapid speed and a “micro” conical rotor brake motor for slow or positioning ...

3. Electric motor - Wikipedia

   en.wikipedia.org/wiki/Electric_motor

   An industrial electric motor . An electric motor is a machine that converts electrical energy into mechanical energy.Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft.

It is powered by 72V 50AH lithium-ion battery. It is powered by 3800 watt, central mounting motor with belt driven , with a speed of 80–90 km/h.

6. Motor constants - Wikipedia

   en.wikipedia.org/wiki/Motor_constants

   The rating of a brushless motor is the ratio of the motor's unloaded rotational speed (measured in RPM) to the peak (not RMS) voltage on the wires connected to the coils (the back EMF). For example, an unloaded motor of K v {\displaystyle K_{\text{v}}} = 5,700 rpm/V supplied with 11.1 V will run at a nominal speed of 63,270 rpm (= 5,700 rpm/V ...

7. Marine propulsion - Wikipedia

   en.wikipedia.org/wiki/Marine_propulsion

   Turbo-electric transmission uses electric generators to convert the mechanical energy of a turbine (steam or gas) into electric energy and electric motors to convert it back into mechanical energy to power the driveshafts. An advantage of turbo-electric transmission is that it allows the combination of high-speed turbines with slow turning ...
