WebPony Motor Starting Method: In this method, a small induction motor known as pony motor is used to bring the motor speed to synchronous speed. After the speed has reached up to its synchronous value, the DC field is switched ON. The motor gets synchronized, and then supply to the pony motor is disconnected. WebFor each species in the reactor there is 1 mol balance equation that yields a differential equation: (4.23) with initial conditions set in the reactor as t = 0, nj = nj0, or Cj = Cj0. If the … WebStarting up the reactor¶ Starting up the reactor is a rather long process, with multiple steps, and can result in you turning into a fine mist if done incorrectly. Rods¶ Before starting the reactor, you need to gather what you'll need to do so. these are the rods, typically found someplace near the console. camping ondres
