Description
Technical field
The utility model is related to a kind of electric machine structure, more particularly to a kind of motor of the complete static seal of carrying magnetic shaft coupling.
Background technology
In the particular applications such as space flight, aviation, underwater, explosion-proof, dust-proof, need to be sealed driving motor, it is ensured that
The normal operation of motor.Currently used motor sealing structure is dynamic sealing and the mode that static seal is combined, and wherein motor turns
Use dynamic sealing mode, non-moving parts junction that O-ring static seal mode, dynamic sealing is used again may be used at dynamic part-output shaft
It is divided into the sealing means such as O-ring dynamic sealing, rotary shaft lip, graphite bearing.But the maximum deficiency of dynamic sealing mode is used to be
There are mechanical frictions at sealing, on the one hand cause the friction torque of motor is big, electric efficiency is low, generate noise, on the other hand by
In the abrasion of dynamic seal, can reduce sealing life and reliability.
Utility model content
It is controllable, high that technical problem to be solved in the utility model is to provide for a kind of small, lightweight, output torque
The motor of the reliable complete static seal of carrying magnetic shaft coupling of efficiency, low noise, sealing performance.
For the technical problem more than solving, the utility model provides a kind of electricity of the complete static seal of carrying magnetic shaft coupling
Machine, motor include motor body, magnetic shaft coupling, casing and end cap；The motor body includes stator, rotor and sealing ring；
The magnetic shaft coupling includes internal rotor and outer rotor, and outer rotor is connect with rotor, and internal rotor is connect with transmission shaft one end,
The connection driving load of the transmission shaft other end, it is completely isolated by end cap between motor body and driving load.
The rotor is hollow structure, and magnetic shaft coupling outer rotor is linked together with rotor fixation, is packed into and turns
In the hollow structure of son.
Static seal is realized using sealing ring between the casing and end cap.
The end cap is made of non-magnet material.
The rotor uses the structure of unilateral duplex bearing, is to shorten axial length to reduce volume.
The torque of the utility model motor passes through magnetic shaft coupling internal rotor and is transferred to driving load；By designing magnetic
Property shaft coupling output torque is, it can be achieved that the controllable effect of motor maximum output torque.
When motor works, machine shaft drives the rotation of magnetic shaft coupling outer rotor, magnetic shaft coupling outer rotor magnetic field and interior
Rotor field interacts, and the rotation of magnetic shaft coupling internal rotor, the rotation of magnetic shaft coupling internal rotor is driven to transmit the torque of motor.
If the transferable torque capacity of magnetic shaft coupling is less than motor exportable torque capacity, magnetic shaft coupling plays limiting motor and goes out
The effect now overloaded achievees the purpose that motor maximum output torque is controllable.
Superior effect of the utility model is：
1）It is connected by magnetic shaft coupling between the utility model machine shaft and load, transmits torque, magnetic shaft coupling
There is no Mechanical Contact between inner and outer rotors, by adding O-ring to be sealed between casing and end cap, realizes motor body and the external world
Between be physically isolated completely；Using static seal mode, it can efficiently transmit torque with simple realization motor inner sealing effect, carry
High transmission efficiency and sealing life, it not will produce noise；
2）For the utility model by adjusting magnetic shaft coupling maximum output torque, realization motor maximum output torque is controllable,
Play the role of protecting motor overload；
3）The utility model uses rotor hollow structure form, motor body shaft to use unilateral duplex bearing mode,
Motor axial length can be shortened；The outer rotor of magnetic shaft coupling is arranged in inside hollow structure, structure space is made full use of,
Shorten motor axial length, mitigates motor weight, reach small size, light-weighted purpose.
