The three factors that determine the type of work a motor can produce are speed, torque, and horsepower. Speed is defined as how fast the motor performs its work. For example, a shaft can rotate slowly or quickly. The typical units of measurement for rotational motor speed are Revolutions Per Minute, or rpm.

This example to explain the concept on the selection of motor is excellent. The author must have experience in designing a conveyor belt in industry.

In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment, moment of force, rotational force or turning effect, depending on the field of study. The concept originated with the studies by Archimedes of the usage of levers. Wikipedia

I think your radius for torque should be from the center of the shaft to the rope windings ; in the first example.

will the calculation method remains same if we use gear motor?
@mostafaabdelmageed4852 4 years ago

what he said is correct >> if you want to maintain any factor of the three factors constant, the other tow shall behave due to the equation .. this what did he mean

There is a mix-up between Power and Energy in this video. Power is defined as the Energy generated or spent over a period of time. Assume you generated 500 Joules over 5 seconds then the average Power generation over these 5 seconds is 500/5=100 Watts. In IS units, the Power unit is Watt=Joule/Sec. In Imperial Units, the Power unit is BTU/hr. Here are few ENERGY conversions (Think of energy as: Joules, BTU, and Kwh i.e. Kilowatt-hour): 1 Joule=0.000947817 BTU=2.7778e-7 Kwh 1 BTU= 1055.06 Joule=0.000293071 Kwh 1 Kwh= =3.6e+6 Joule = 3412.14 BTU ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Here are few POWER conversions (think of Power as: Watts, Mechanical Horsepower hp(i), 1 Watt=3.412141 BTU/Hr=0.0013410 hp(i) 1 BTU/Hr= 0.2931 Watt=0.000393 hp(i) 1 hp(i)= 745.67 Watt = 2544.433 BTU/hr

The Torque definition is not properly explained?????
@dhruvalsharma6631 6 years ago

Hp is constant how can it be increased or decreased?
@davenkenya4298 8 years ago

good explanation
@javiervidoza8424 2 years ago

You have to be careful with the equivalent units. HP is equivalent to Btu/hr or Watts. Do not mixed Work units with Power Units
