SJ Series-Extruder Permanent Magnet Direct Drive Motor
Plastic extrusion molding is one of the important molding methods of plastic molding. Most thermoplastics can be processed by this method. Extrusion molding has the following characteristics:
● Continuous production process, high production efficiency
● Wide range of applications, can produce pipes, bars, plates, films, monofilaments, wires, cables, profiles and hollow products.
Extrusion molding products can be widely used in people's daily life and agriculture, construction, petrochemical, machinery manufacturing, national defense and other industrial sectors.

Advantages of permanent magnet motor to Gangbao extruder
• Directly coupled with the load, reducing the maintenance workload of the mechanical transmission mechanism
• High efficiency operation over full speed range and wide load range
• The motor adopts oil cooling, low temperature rise, low noise, large torque per unit volume
• Independent thrust package design, installed outside the motor, easy maintenance, not affected by shaft current
Additional thrust bearing and independent cooling bearing seat can be assembled separately from the motor and automatically centered on the shaft, which is convenient to replace the bearing and can protect the motor from being damaged by the force of the screw.
• Thrust bearings can also be replaced by hydrostatic bearings, longer life, smaller friction and more energy saving
• Hollow shaft design, suitable for plastic and other industry requirements, easy screw disassembly
• Using resolver as speed feedback, suitable for large vibration occasions
Disadvantages of traditional extruder motors
• DC motor maintenance difficulties, time to change the carbon brush cost is high
• The deceleration mechanism is difficult to maintain and the regular oil change is expensive.
• Bulky space, complex installation, noise
• Low overall efficiency and high energy consumption
