Electrical news and engineering . ro-per order, and so that if one motor stops all other motorspreceding it will stop also. This arrangement is very sim-ple and with it the mill can be started up in much less timethan is the case with a steam driven mill. Push buttonstations may be located at convenient points so that an en-tire mill section may be stopped by simply pushing a buttonat any one of them. In the grain elevators, electric drive is particularly ap-plicable. The motor or motors can be located close to themachinery, again cutting down belt expense and powerlosses in transmission. Ordinarily motors are supplied foreach elevator leg, car puller and exhaust fan, while the low or moderate speed and are designed for constant speedservice, ll a single motor is used without a friction clutchfor a group drive it should be of the slip ring type, if alter-nating current, or compound wound direct current, but ifa friction clutch is used the motor may be either of thesynchronous or squirrel cage type. The most common ar-. A 600 2300 volt synchronous motor with rope drive rangement for group drives is the use of the squirrel cagemotors with a friction clutch where that is necessary. The use of motors not only reduces the friction lossbut cuts down the first cost of shafting and helting, reducesthe labor costs of maintenance, replacement and repairs,and results in cleanliness and safety in operation beyondthat obtained with other drives. .-Vn electric motor is comparatively compact and it is
