Pump vs Motor
Pump and motor are two devices that are widely used in many industries. The motor is a device that is capable of rotating when a voltage is applied. The pump is a device that is used to move fluids. Both of these devices are very important in fields such as electrical engineering, mechanical engineering, civil engineering, constructions, robotics, automobile engineering and numerous other fields. In this article, we are going to discuss what motor and pump are, the operational principles behind motor and pump, the types and variations of motors and pumps, and finally the difference between motor and pump.
Motor
Electric motor, which is more commonly known as the motor, is a device that is capable of converting electrical energy into mechanical energy. Electric motors are divided into two categories based on the form of electricity on which it runs. These two types are DC motors and AC motors. DC motors run on direct current and AC motors run on alternating current. Most electric motors are based on time varying magnetic fields. The axel containing all the moving parts of the motor is known as the armature. The rest of the motor is known as the body. The motor has time varying magnetic fields that are produced by induction coils. In a typical DC motor, the coils are placed at the armature of the motor. In most of the AC motors, the coils are placed on the body of the motor and the armature is composed of permanent magnets. There is also a third type of motors known as universal motors. Universal motors are capable of running on AC voltage and DC voltage alike.
Pump
A pump is a device that is used to move fluids. Pumps use mechanical energy to transfer these fluids. The most common example for the pump is the air compressor. It takes air from outside and transfer it to the inside overcoming the pressure of the gas inside. The pump is the device which does the work on the fluid in order to get it to a higher energy or entropy state. Most of the mechanical pumps are based on a rotary motion. There are pumps that operate on a linear motion too. Most pumps are driven by either electric motors or fuel engines. A pump does not convert energy to different forms; it rather directs the energy on a desired way. Some energy is always lost as sound, vibrations, and heat; therefore, a pump is not 100% efficient. The three main types of pumps are known as direct lift pumps, displacement pumps and gravity pumps.
What is the difference between a Motor and a Pump?
• A pump does not convert one form of energy to a different form of energy, but the Motor converts electrical energy to mechanical energy.
• A pump requires a driving mechanism such as a motor or an engine to operate. The motor only requires an energy source.
