Hammerhead tower crane also called Topkit Tower Cranes is the tower crane with tower head. The tower head is the fulcrum of tie-bars chains connected to jib and counter jib. This tower crane design makes good advantage of the prosperity of bending vulnerability and pressing invulnerability and lowers the weight of jib & counter jib (simple transforming beam in mechanical model). This type of tower crane is lower in production cost, but is more demanding on the erecting and dismantling...
1. The air gap between the stator and rotor is very small, which is easy to lead to the collision between the stator and rotor. In medium and small motors, the air gap is generally 0.2mm ~ 1.5mm. When the air gap is large, the excitation current is also large, consequently affects the power factor of the motor. If the air gap is too small, the rotor may occur the friction or collision.Generally, due to the serious out-of-tolerance of bearing and the inner hole of the end cover is out of shape...
