Abstract
The utility model discloses a special motor for an instrument truck. Thickness of a rotor end ring body of the motor is obviously getting thinner. An enameled wire of a rotor winding is a QZY-2 circle copper enameled wire (F grade). And cooling blades are disposed on a motor rotor. The beneficial effects of the special motor for the instrument truck are that thickness reduction of the rotor end ring body helps to effectively reduce starting-up current of the motor, thereby reducing heating degree; an insulating material is improved to the F-grade insulating material from a B-grade insulating material, and thus heat resistance grade of the motor is improved, and the motor is not easy to get burned during frequent starting up processes, and therefore an effect of prolonged service life of the motor is achieved.
Description
Technical field
The utility model relates to a kind of measuring truck motor, belongs to the mechanical ﹠ electrical technology field.
Background technology
YD series standard design motor uses the instrument lathe at Fraquent start, and when boring tapping machine work, will burn out less than 1 ~ 2 week useful life.The GUD serial motors is according to the design of the production characteristics of measuring truck motor, and YD series is when frequent motor starting, and causing starting current is 5 ~ 6 times of operating current, causes motor to burn out.
The utility model content
The purpose of this utility model is in order to solve the existing defective of easily burning of instrument vehicle motor in prior art, to provide a kind of security and stability to solve the problems referred to above by the measuring truck motor.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of measuring truck motor special comprises the rotor-end ring body, and wherein, the thickness of described rotor-end ring body is 2.0-3.5mm, as 0.55,0.75, four specifications of 1.1,1.5KW, end ring thickness is 2.0mm, 2.2,3.0, be 2.5mm during 4.0KW, 5.5, during 7.5KW, thickness is 3.5mm.
As preferred version, motor of the present utility model also comprises cooling fan.
As preferred version, motor of the present utility model also comprises stator winding, and the enamel insulated wire of described stator winding is F class F insulation enamelled wire.
Further, described F class F insulation enamelled wire is QZY-2 circle copper enamelled wire.
Principle of the present utility model is the motor repacking with measuring truck, the parts such as support, stator are all with reference to YD series, the thickness of rotor-end ring body adopts the thickness of the rotor-end ring body of y series motor, in addition, the type of cooling adopts the IC416 type of cooling, has added independently cooling fan at motor rear end part.
The utility model has the advantages that: the thickness of rotor-end ring body reduces to effectively reduce the starting current of motor, thereby reduce the degree of heat, be replaced by QZY-2 circle copper enamelled wire (F level) by QZ-2 (B level) enamel insulated wire, improved temperature resistant grade, thereby guarantee that motor is in the frequent starting process, be not easy to burn out, reach the effect of the prolongation in useful life of motor.

Embodiment
Further understand and understanding for making architectural feature of the present utility model and the effect reached are had, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
Referring to Fig. 1 and Fig. 2, rotor 1, the first deep groove ball bearing 3, winding stator core 5, cooling fan 7, fan housing 8, the second deep groove ball bearing 9 are arranged; Above-mentioned housing comprises front end housing 2, support 4, rear end cap 6; Above-mentioned support 4 two ends are fixedly connected with rear end cap 6 use bolts with above-mentioned front end housing 2 respectively; Above-mentioned rear end cap 6 other ends are fixedly connected with above-mentioned fan housing 8 use bolts; Above-mentioned have winding stator core 5 to be arranged in above-mentioned housing; Above-mentioned the first deep groove ball bearing 3 and the second deep groove ball bearing 9 are separately positioned on the shaft shoulder at above-mentioned rotor 1 two ends; Above-mentioned rotor 1, the first deep groove ball bearing 3, the second deep groove ball bearing 9 cooperatively interact and are arranged in above-mentioned housing; And drop in the space 10 of above-mentioned fan housing 8.Above-mentioned the first deep groove ball bearing 3 is equipped with in the first groove 15 of above-mentioned front end housing 2 with the wave mode packing ring, and above-mentioned the second deep groove ball bearing 9 is equipped with in the second groove 16 of above-mentioned rear end cap 6 with the wave mode packing ring.Above-mentioned support 4 one sides also are provided with terminal box 11.Above-mentioned support 4 centre positions, upper end are provided with suspension ring 13.Above-mentioned rear end cap 6 lower ends also are provided with support 12.
Referring to Fig. 3, the outer rotor-end ring body 17 that is socketed with aluminium matter of above-mentioned rotor 1, when the motor model was GUD132S-8/4, the thickness of rotor-end ring body 17 was reduced to 3.5mm by original 12mm, when the motor model was GUD80, the thickness of rotor-end ring body 17 was reduced to 2.0mm by original 10mm.
When motor adopts YD132S-8/4, power 2.2/3.3KW, starting current times reduces, standard design is 5.2 times when 4P, and 4.0 times of GUD designs are when 8P, be reduced to 3 times by original 3.6 times, the type of cooling is IC416, just carries out the balanced wind that carries out when motor is on duty cooling, so just effectively reduces the degree of heat of motor.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification is principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
