As the industrial arena grows more sophisticated, it seems as though operations are confronting fewer and fewer broken machine shafts. When shafts DO break, however, there are almost always as many theories regarding the suspected culprits as there are people involved. Fig. 1 The appearance of an overload failure depends on whether the shaft material …
Continous start and stop:- Group drive can be used with advantage in those industrial processes where there is the sequence of continuity in operation and where it is desirable to stop these processes simultaneously as in a flour mill. Ques 6. The disadvantages of group drive electric machine is/are. Answer 3.

Motor Sizing. Proper sizing and selection of a motor for your equipment is key to ensuring performance, reliability and cost of the equipment. In addition to the information below for properly sizing a motor, Oriental Motor offers online motor sizing tools as well as assistance from our Technical Support staff.
Power requirement is very high. Speed control ratio is 1:10. Very low creeping speeds of 1 rpm may be required. Starting torque should be in the range 200 to 250% of full load torque. The acceleration of the drive should be completed in about 15 s. For small periods an overload capacity of 200-250% may be required.
Customer Satisfaction Scale of 1-100 Customer satisfaction means that customer expectations are met. This requires a combination of conformance to requirements (the project must produce what it said it would produce) and fitness for use (the product or service produced must satisfy real needs). The Customer Satisfaction Index is an index
the highest speeds attainable (within the pitch diameter range) • Recommended on 4 cycle engines 8 - 18 hp • Symmetrical drive belt: 7/8" top width • Drive clutch bore size: 1", 1/4" key • Drive clutch engagement range: 1600 rpm minimum, 2600 rpm max • Speed reduction ratios using 40D, 7-1/2" diameter - 2.43:1 low, 1:1 high,
7. Slip Ring Induction Motor. It has high starting torque and large overload capacity. The speed of slip ring induction motor can be changed up to 50% of its normal speed. Slip ring induction motor is used for those industrial drives which require high starting torque and speed control such as lifts, pumps, winding machines, presses, line shafts, elevators and …

For All-Wheel Drive vehicles, keep the full charge limit of the battery to under 90% for daily use by using the mobile app or vehicle's touchscreen to set charge limit within the 'Daily' range. If you need the full range (i.e. ) of your battery for a long-distance trip, you can increase the limit to the 'Trip' range (>90%) as ...

Hägglunds drive systems– a success at the Aitik mine The feed system solution offered by Bosch Rexroth was two Hägglunds CBm motors per apron feeder. It was a welcome solution that easily met the requirements. Brazilian sugar producer Usina Ferrari puts high trust in the Hägglunds hydraulic direct drives that crush its cane.
Figure 6: Torque-vs.-speed diagram of the IM (5) There are only limited control possibilities for grid-connected induction motors. The slip-ring rotor allows the connection of external resistors to the rotor circuit. The dependence of torque-speed characteristics on rotor resistance is shown in Figure 7.
