What must be done to cause the motor to begin operating as a squirrel-cage motor?arrow_forwardForced Induction – For combustion engines, two main types of forced induction (or pressure charging) are used: Supercharging and Turbocharging. Both methods compress the inlet charge substantially above atmospheric pressure before the point of ignition. The compressed charge will become more dense which will create an increase in power and torque from a similar sized naturally aspirated engine. It is worth noting that on high speed vehicles (Formula One) a ram-air effect forced induction can be achieved using intake tube(s) directed into the on-coming air. This can be seen on race cars where the intake is above the drivers head for unrestricted flow or on racing motorbikes where the intake is positioned in the front fairing. Draw a schematic diagram of a supercharged engine and a turbocharged engine layout:arrow_forward
