7 İ stanbul Technical University Types of Power Transmission 1. Mechanical Power Transmission: • Power is transmitted by mechanical power trans. elements • Power trans. is done by means of either friction or positive contact between surfaces of contacting mechanical elements 2. Electrical Power Transmission: • Electrical power which is generated using mechanical means is transmitted using wires and brought close to the working machine which is an electric motor. • Electric motor, then converts the electric power to mechanical power again

8 İ stanbul Technical University 3. Hydraulic Power Transmission: • Mechanical power is used to rotate a hydraulic pump to obtain compressed oil • Compressed oil is sent to the working machine through hoses or pipes • Compressed oil is the used to rotate an hydraulic motor, or activate an hydraulic cylinder, and at the end of the mechanical power is obtained again • e.g. Hydraulic presses
