How long will it take a 2 5 KW motor to lift a 80 kg block 30 m high?

How much weight can a 1 HP motor lift?

The constant 1 horsepower equals 550 foot-pounds per second. In other words, 1 horsepower is the amount of work required to move a load of 550 pounds over 1 foot, in 1 second.

How do you calculate the power needed to lift a load?

Let us calculate the work done in lifting an object of mass m through a height h. If the object is lifted straight up at constant speed, then the force needed to lift it is equal to its weight mg. The work done on the mass is then W = Fd = mgh.

How much weight can a dc motor lift?

The maximum torque is given as 1.2 kg*cm (which includes the gearbox-transition), which means having wheels with an radius of 1 cm (or 2cm in diameter) will give you a force that is equivalent to 1.2 kg in weight at nominal voltage, as long as your electronics can provide a current of 300 mA (load current).

How do you calculate the power needed for a motor?

A watt (W) is a unit of power defined as one Joule per second. For a DC source the calculation is simply the voltage times the current: W = V x A. However, determining the power in watts for an AC source must include the power factor (PF), so W = V x A x PF for AC systems.

How much weight can a 3/4 hp motor lift?

Typically, a 1/2 hp garage door opener can lift up to 300 pounds of weight without putting too much pressure on the motor. On the other hand, a 3/4 horsepower opener can lift a mighty 600lbs!

What is the weight of 2 hp motor?

Product Specification

Power 2 HP
Frame 125MM
Material Cast Iron

Shaft 28.5 MM

How much weight can a 1/2 hp motor lift?

A 1/2 horsepower garage door opener can lift approximately 300 pounds, which is the average weight of a two-car steel door. A one-horsepower opener can easily lift approximately 400 pounds. The greater the horsepower, the faster the opener can lift the door, although some are designed to lift faster than others.

What is the average power required to lift a mass of 100kg to a height of 50m in 50 seconds?

980 J/s.

Which motor used in lifts?

Lifts are preferred by AC slip ring or DC compound motor. In case of single phase installation, the commutator motors are preferred. Variable Frequency drive electronic controls are used in the latest lift designs.

How strong is a 12V DC motor?

The 12VDC Motor that we construct is rated from fractional horsepower to 2 HP, running at speeds up to 5,000 RPM. These 12V DC Motors can also be designed for applications that require different voltages, such as 24 Volts, 36 Volts, and others up to 180 Volts.

How do you calculate the power of a DC motor?

Power Equation of a DC Motor

  1. VIa = Input Power supply (Armature Input)
  2. EbIa = Mechanical Power developed in Armature (Armature Output)
  3. Ia2 Ra = Power loss in armature (Armature Copper (Cu) Loss)

How much weight can a 3 HP motor lift?

Manufacturers have added excessive force auto shutoff and a nylon gears that fail when too much force is exerted. Actual figures are closer to 125 lbs for a 1/2 HP and 175 lbs for a 3/4 HP.

How do you convert kW to rpm?

kW = 0.105 x Nm x rpm / 1000. Example: A three-phase induction motor can provide 144Nm at 1480 rpm. Calculate the motor rating in kilowatt.

What is the rpm of 1 hp motor?

1 HP Single Phase Electric Motor, For Industrial, Speed: 1440 Rpm.
