![]() The larger the slip, the more torque the motor will produce, to a point. This speed difference, called "slip" gives rise to a current in the rotor which then generates torque. In this case, 3600 RPM would be called the "synchronous speed." Meaning that if the rotor actually was spinning at 3600 RPM, then the rotor and rotating field are in-sync.īut in normal motoring operation, the rotor spins a bit slower than 3600 RPM. If you consider a two-pole motor running on a 60 Hz system, the rotating field moves at 60 Hz * 60 sec/min = 3600 RPM. ![]() In an induction motor, the supplied voltage creates a rotating magnetic field around the rotor. ![]() If I decelerate a motor does that mean I have to mechanically stall its shaft and it will cause regeneration? What can be an example to deceleration in this context? How does such braking happen so that it causes regeneration? But the info says this regeneration will take place if a high inertia load is decelerated. I can understand first examples where a crane or an elevator is lowering a load it acts as a generator. In the rotating mass flows back through the motor to the drive. If a high inertia load is decelerated in this case, the energy stored Regeneration, as it is called, will also take place Occur if the load is giving up energy, such as when a crane orĮlevator is lowering a load, or maybe when a conveyor is transporting Is, from the load, through the motor, back to the drive. However, occasionally the energy flow will be in reverse, that Most of the time, in most applications, a variable frequency driveĬontrols the motor by supplying it with energy which then powers the Here is an info about regeneration due to braking:
