The minimum speed of 6v motor to produce electricity is 15 Mph.
The minimum wind speed required to produce wind energy is typically around 7-10 miles per hour. This is the speed at which most wind turbines start generating electricity efficiently.
it is kept at minimum position to produce more torque which is required for starting a motor
it is the difference between the synchronous and asynchronous speed of a induction motor
Typically, wind turbines need a minimum wind speed of about 6-9 mph (3-4 m/s) to generate electricity. This is known as the cut-in speed. At this speed, the turbine blades start rotating and generating power.
The regulator that controls the speed at which the sexual organs produce ejaculation.
A typical wind turbine starts generating electricity at wind speeds around 6-9 miles per hour (mph). The most efficient electricity generation occurs at wind speeds around 25-30 mph. Below 6 mph, wind turbines may not produce any electricity.
The regulator that controls the speed at which the sexual organs produce ejaculation.
initial torque to overcome the friction in generator and then to keep constant speed of stator within the generator. Minimum 50NM
Through a restrictive process of limiting the amount of electricity to the fan motor.
Ceiling fans use less electricity on low speed than they do on medium and high speed. Capacitors are used to control the various fan speeds. The capacitor limits the amount of electricity supplied to the fan motor. When less electricity is sent to the windings in the motor, the fan spins at a lower RPM. The result is a slower speed and less airflow. However, some fans move almost no air at low speeds, so it is important to know what the CFM/watts is for the ceiling fan in question so you can compare the performance at any given speed relative to the amount of electricity used
In series motor, At no Load Condition the flow of Armature Current is low, then the Flux is also low. Flux is inversely proportional to speed. If flux is decrease the speed is rapidly increase it spoil the rotor parts...... so SERIES MOTOR is start with LOAD.....
The output from the dynamo varies with the speed of the bicycle. And as a geared bicycle is likely(but don't have to) travel a bit faster than the single speed, it may produce a bit more electricity.
