Machine can be defined as the cluster of mechanisms that can perform certain task by expanding energy. Majority of the machines are driven be mechanical power, which is nothing but torque of rotational shaft. A prime mover is used to convert other form of energy to mechanical energy. For example, an electric motor converts electric energy into mechanical power. However, such prime movers are located away from the machine unit

Machine can be defined as a cluster of mechanisms that can perform certain tasks in a pre-defined way by expending energy. Most functions of a machine are carried out by utilizing mechanical power, which is supplied by prime movers. A prime mover can convert one form of energy to mechanical energy (in the form of rotational torque). First and foremost example can be electric motor, where electrical energy is converted

Machine is a cluster of mechanisms that requires source of energy to perform certain task in a pre-defined way. Household or industrial machineries are mostly driven with the help of prime movers (such as electric motor, windmill, hydraulic or steam turbine, internal combustion engine, etc.). Usually this prime mover is located away from the machine unit and rotates at higher speed than it is required in machines. Mechanical power transmission

A prime mover is used to generate mechanical energy by converting from other form of energy. For example, electric motor converts electrical energy to mechanical energy and delivers the same in the form of shaft rotation. Similarly, hydraulic turbine, steam turbine, wind mill, etc. can also act as prime mover. Mechanical drives are used to transmit motion, torque and power from such prime movers (driver shaft) to machine parts (driven

Mechanical power transmission system is utilized to transmit mechanical power (in the form of rotational torque) from a driver shaft (such as prime mover) to the driven shaft (like machine unit). Belt drive is one of the mechanical drives (others being gear drive, chain drive and rope drive) that is used to transmit motion, torque and power from one shaft to another. Initially pulleys of required diameter are rigidly mounted

Every machine requires a source of energy to perform certain task. Electric motor is predominantly used as power source for industrial machineries. Apart from electric motor, other prime movers such as steam turbine, hydraulic turbine, wind mill, etc. are also used in some specific applications. Mechanical power transmission system retrieves mechanical power from such prime movers and subsequently delivers the same to the machine unit. It can also change the

A machine is composed of mechanisms. These mechanisms provide relative motions that can be utilized to perform certain task with minimal intervention. All these mechanisms essentially require a source of power to perform the intended work. This power source can be human power; however, in 21st century with the fourth industrial revolution (Industry 4.0) in rolling, elimination of human power requirement to drive a machine is one obsolete idea.
