Wound field DC motors 4 (series, shunt or compound) are used in industrial environments for coil feeding reels in the milling/metalforming, crane hoists, motor-driven cable reels, and elevator hoist motors.
Why is DC series motor used in Crane?
The starting torque of the DC series motor is proportional to the square of the armature current. … That is why DC series motor is capable to produce high starting torque, and it is preferred for driving heavy loads. The high inertia loads like cranes need a high starting torque. The DC series motor is used in cranes.
Which motor is used in lift?
AC slip ring or DC compound motors are prefer for lifts. Shunt type commutator motors are preferred in case of single phase installation. The latest lift designs use 3-phase induction motors with variable frequency drive electronic controls.
Which type of motor is used?
AC brushless motors are some of the most popular in motion control. They use induction of a rotating magnetic field, generated in the stator, to turn both the stator and rotor at a synchronous rate. They rely on permanent electromagnets to operate.
What is used in crane?
The most important substance used to manufacture cranes is steel. Steel is an alloy of iron and a small amount of carbon. For structures that do not require very high strength, a common form of steel known as carbon steel is used. By definition, carbon steel contains less than 2% of elements other than iron and carbon.
What are the applications of DC motor?
Applications. DC motors are suitable for many applications – including conveyors, turntables and others for which adjustable speed and constant or low-speed torque are required. They also work well in dynamic braking and reversing applications, which are common in many industrial machines.
What are the 3 types of DC motors?
Types of DC Motors. There are 3 main types of DC motor that are available:- Series, Shunt and Compound. These terms relate to the type of connection of the field windings with respect to the armature circuit.
How much weight can a 1 hp motor lift?
This means with 1 hp, you can lift about 550 lbs (250 kg) at a rate of 1 ft/sec, 1100 lbs at a rate of 0.5 ft/sec, 225 lb at a rate of 2 ft/sec, 1 lb at a rate of 550 ft/sec, and so on.
Why is the DC motor preferred over AC motor?
DC motors have the advantage of: higher starting torque, quick starting and stopping, reversing, variable speeds with voltage input and they are easier and cheaper to control than AC. AC motor advantages include: lower power demand on start and minimal maintenance.
Which motor is used in EOT crane?
While series DC motors consume more power than PMDC motors to produce their electromagnetic field, they’re powerful, efficient at high speeds and produce the most torque; hence, they are used for heavy duty winches. Shunt DC motors are used in constant speed applications, 18 such as reel drives.
Which motor is used in fan?
In conventional ceiling fans, single phase induction motor is used. These motors consume minimum power and hence, are also known as fractional kilowatt motors. A single phase induction motor requires only one power phase for operating. It converts the electrical energy from the power input into mechanical energy.
What are the three types of motors?
Each motor has a specific application. Basic motors have been classified into three distinct types: AC motor, DC motor, and specialized motors.

What is the main purpose of a crane?
A crane is a machine that is used to lift and move heavy loads, machines, materials, and goods for a variety of purposes. They are used in all different sectors of industry, from construction to manufacturing to shipbuilding and material loading.
Who will use the crane with an electromagnet?
In large industrial cranes, extremely strong electromagnets are used to lift heavy objects off the ground and transport them from one place to another. Steel storage crates containing cars or manufacturing machines heavily rely on cranes to be placed onto ships before they are transported overseas.
