Q.8. What are the various factors that influence the choice of electric drives? [2]
Answer
Choice of electric drive is influenced by factors including: the nature of load (constant torque, constant power, fan/pump-type variable torque), required speed range and speed control accuracy, starting and braking torque requirements, duty cycle (continuous, intermittent, or short-time), efficiency and power factor considerations, capital and running cost, size and space constraints, environmental conditions (temperature, dust, hazardous atmosphere), and reliability/maintenance requirements of the driven application.
