1. braking energy required for the drive cycle: A very known principle of law conservation of energy states that energy cannot be created nor be destroyed hence using this principle we calculate braking energy as follows: initially, the vehicle will be moving i.e it will be having some kinetic energy when the brake is…

1. induction motor operation is similar to the clutch   torque on the driving shaft = torque on the driven shaft. In fact, these two torques are actually one and the same torque, because the torque is caused by friction between the discs and it is true whether the clutch is slipping or not. Let ω1 and ω2…
