Abstract
The utility model relates to a three-phase ultra high-speed electric machine, which is the improvement of three-phase electric machines. The utility model is characterized in that two ordinary three-phase electric machines are connected with a second electric machine into a whole by a spline connection shaft at the end of a first electric machine. Two high-speed bearings are arranged on the exterior of the connecting shaft of the second electric machine, and the output spindle nose on the other end is also provided with two high-speed bearings. The power cord led out from the four high-speed bearings conducts current to operate the second electric machine. The utility model is used for high-speed rotation power equipment, accelerating electric machines by more than two times.
Description
The utility model patent is the improvement to three phase electric machine, is a kind of three-phase ultrahigh speed motor.
At present, existing three-phase common electric machine is a squirrel cage motor, and its revolution maximum is no more than 3000 rev/mins, inefficiency.The utility model is with two common three phase electric machines, spline connecting axle by the motor end links into an integrated entity, by four bearings second motor is fixed in the motor fixed muffle, by the circumscripted power line conduction of drawing on the bearing, make second motor rotation, can make the motor speedup more than one times.
The utility model purpose is to provide a kind of novel three-phase ultrahigh speed motor for the high speed rotating power-equipment.
The utility model three-phase ultrahigh speed motor content Description:
The utility model three-phase ultrahigh speed motor, it is characterized in that forming by two common three phase electric machines, spline connecting axle and second motor by first motor end link into an integrated entity, the outside of second motor connecting axle is provided with an insulating case, two high-speed bearings are arranged on it, also be provided with two high-speed bearings on the output shaft head of the other end, by these four high-speed bearings second motor is fixed in the motor fixed muffle, between two high-speed bearings, be provided with insulation spacer, make second motor rotation by the conduction of the extracting power supply cord on four high-speed bearings.
The utility model three-phase ultrahigh speed motor can be used for the high speed rotating power-equipment, as sanding machine, carpenter's process equipment, electric tool etc., can make the motor speedup more than one times ， And can improve the operating efficiency of motor.
