Long-Timely Hindered Rotation Torque Motor Type Cable Drum (P20)

Long-timely hindered rotation torque motor type cable drum electrical data and features:
1.1 The cable is invariable to tension among the full coil bar from empty one, applied to under the working situation of long-timely low-speed, frequent operating in positive and oppose rotation.
1.2 Different from general motor is that it supplied with small current and it can long -timely hindered rotate, reverse rotate.
1.3 It has tested in 8-10 hours hindered rotation before assembling, the motor rises warmly < 65K in hot state, hindered rotation torque decreases in 5% of the ranges.

Brake consists of magnetism yoke, excitation coil, spring, brake disc, armature, gear wheel cover, manual releasing the device, screw etc.
The brake is installed and covered in the back of the motor, adjusting and installing screw reach suitable air (space) crack value, and brake disc and gear wheel cover band motor drive shaft.
When excitation coil of brake being at putting through the rated voltage, the electric magnetic force sucks the armature, making armature be independent from brake disc (release). The axle of the motor drives brake disc being under normal operation, when the motor cuts out, and the brake cuts out at the same time too, the spring oppressing the armature at this moment which forcing between brake disc and armature and ring flange produce the torque of friction, making the axle of the motor park to rotate fast.

2, Electricity (the signal) transmitting part
Collector ring chamber can be divided into power and signal transmission from usage, and can be divided into 380V, 500V, 3KV, 6KV, 10KV, etc. According to the grade of voltage.

Cable capacity part
Spool: Can be divided into many row and single row twined, To facilitate transporting, spool of diameter ≤ 2.4m is whole structure; >2.4m are parts, assembling on- site.

Cable drum operation principle:
Long-timely hindered rotation type which the power part of cable drum and regulating speed part beared by motor with uniqueness electrical and mechanical, which has a wide of speed adjustment and softer mechanical characteristics. The corresponding change of the rotational speed of the motor happens when changing in load, namely load increases the rotational speed to drop, load drops the rotational speed raises. It features all long and steady operation at whatever of their torque and rotational speed of mechanical curves. So can guarantee the cable obtain proper coiling speed and pulling force on the corresponding radius.
1. Coiling up: Cable motor outputs torque as power force, coiling up cable by reductor running the spool to coil up cable.
2. Release cable: Motor leaves strength of hindering from torque, preventing the cable from drawing spool fast, it guarantees putting synchronous of releasing cable.
3. When machinery shutting down, long- timely motor have plate type often close brake, which can guarantee the cable will not back fall from a plate for the action of the gravity when power cutting off.
