Granulators - an overview | ScienceDirect Topics
Hammer mills accomplish size reduction by typically impacting at rates of 7000 rpm and higher [16]. A solid rotor for grinding scrap Cu wires, PCBs, metals, and plastics is used. These granulators are used for the sizing of plastics, nonferrous metals, heterogeneous materials, and enable to reach controlled output size in the recycling process ...
Soft Starter In Industrial Applications
Danfoss VLT® Soft Starter – Applications like pumps, conveyers, centrifuges and bandsaws must be started slowly, and sometimes stopped slowly, to prevent mechanical shocks such as water hammer, and strains on bands, couplings and shafts. Motors selected from a standard range are almost always chosen with a rated power in excess of maximum ...
Medium voltage soft starter for heavy-duty motor control …
A soft starter is an electronic motor controller used on three phase medium voltage squirrel cage induction motors. During motor starting, the soft starter controls the voltage or current supplied to the motor. Motor start performance is optimized by reducing the total start current while optimizing the torque produced by the motor.

Starting method | KSB
The squirrel-cage motors used for centrifugal pumps (see Asynchronous motor) have high starting currents. For motor ratings below 4 kW, the DOL starting and soft starting methods are used, while the star-delta, auto transformer, soft starter and frequency inverter methods are preferred for motor ratings above 4 kW. DOL starting For DOL starting, the three motor …

In order to limit the starting current of the motor, star-delta starting can be used for grid fed induction machines. The induction machine is started in star connection and later switched to delta connection. This reduces the starting peak current to one third (see Figure 9). However, the starting torque is also reduced to one third.

Current motor starting methods: Advantages and disadvantages. Inside Machines: In low- and medium-voltages, three-phase induction motors are the most widely used, due to availability, simplicity, robustness, and low cost. Starting and stopping "industrial-standard motors" and other operations present great challenges for many companies.
Starting methods of three phase induction motors ...
An induction motor is similar to a poly-phase transformer whose secondary is short circuited. Thus, at normal supply voltage, like in transformers, the initial current taken by the primary is very large for a short while. Unlike in DC motors, large current at starting is due to the absence of back emf.If an induction motor is directly switched on from the supply, it takes 5 to 7 times its …
