Description
Technical field
The present invention relates to a kind of motor, more particularly to a kind of air-cooled servomotor.
Background technology
Servomotor is one kind of motor, because its have the characteristics that control accuracy high and low frequency characteristic is good, overload capacity is good and
It is widely used in numerical control system.Because servomotor can produce stator copper loss, iron loss, added losses in normal work
And rotor loss etc., these losses can all make motor casing generate heat, that is, temperature rise phenomenon is produced, in the ideal situation, if can be by electricity
Heat caused by machine completely distributes at any time, i.e. when the temperature rise of motor is zero, as long as the mechanical strength of motor can ensure,
Motor can export the power of infinity, therefore the heat dispersion of motor determines the size of power of motor, that is, improve motor and dissipate
Thermal effect is the important channel for improving power of motor, and conventional motor is coaxial generally by the outboard end in rotor axis of electric
A fan blade is fixed, rotor axis of electric drives fan blade synchronous axial system to carry out wind cooling temperature lowering to motor, due in fan blade blow-through motor
One end of chamber, area of dissipation is small, and cooling effect is poor, significantly limit the lifting of power of motor.
Chinese patent discloses a kind of air cooling means of dynamo（CN2912090Y）, it is by cooling motor, fan blade, blade cover group
Into openend and the motor housing of blade cover are fixed, and cooling motor is located in the inner chamber of blade cover, is fixed on the end face of blade cover
On.Although this device is that a cooling motor is separately provided in one end of motor, air quantity caused by cooling motor is still concentrated
In one end of motor, therefore equally exist that area of dissipation is small, and cooling effect is poor, significantly limit the skills such as the lifting of power of motor
Art problem.
Chinese patent discloses a kind of air cooling equipment of servomotor（CN 102332782A）, including servomotor, rear method
Orchid, air-cooled casing 1, centrifugal blower on rear flange and coaxial cover sets the Air cooler of a tubular on the outside of the casing of motor
Shell 2.Now, annular passage is formed between the leading section of air-cooled casing and casing, when centrifugal fan operates from the opening at rear portion
Suck radially exiting after air, this radial air flow and air-cooled casing inner wall collision rift carry over annular passage to front side flow again,
The whole casing surface of airflow passes, form radiating.The constructional appearance is clean and tidy, compact-sized, but due to taking 8 aluminium section bar knots
Structure is put together, and due to aluminium extrusion characteristic, aluminium section bar is in aluminium extrusion drawing process, it may occur that a certain degree of deformation, causes
Air-cooled casing split is difficult, and installation fixation is all not easy, simultaneously as needing to mold manufacture, mould takes then tens thousand of members, because
This this kind of mode cost is higher, is unfavorable for promoting the use of.
In summary situation, design one kind can avoid above prior art shortcoming, and have rational in infrastructure, manufacturing process
The novel air-cooled servomotor of the features such as easy, easy for installation is necessary.
