Devices for starting, controlling, and protecting electric motors.

Extract from Specification.—This invention consists, as to main features thereof, in means which ensure, in an improved manner, that when the motor has been switched on resistance will remain in circuit until the speed of the armature has increased, and the current in the circuit consequently decreased, to a predetermined amount, and that when this point is reached the resistance will become automatically short-circuited; and in means which ensure that in the event of the load becoming excessive the increased current will cause resistance to be brought in and remain in until the current in the circuit decreases to the predetermined amount above referred to, when the resistance will be automatically short-circuited. The above objects are effected, according to an important feature of this invention, by means of a movable iron member which is acted upon magnetically by a solenoid. (Specification 19s.)
