Brief Introduction

45 kW DC motor (Brushed DC Motor) is a kind of motor that realizes the direction conversion of current through brushes and commutator. Its working principle is to utilize the principle of electromagnetic induction to convert electrical energy into mechanical energy. The structure of 45 kW DC motor (Brushed DC Motor) is relatively simple, mainly consisting of stator, rotor, commutator and brushes. Due to their simplicity of design and low cost, 45 kW DC motor (Brushed DC Motor) is widely used in many applications.

In modern manufacturing industry, extruder is an important equipment, widely used in plastic, rubber, food and other industries. The performance of the extruder directly affects the quality and productivity of the product. And among the core components of the extruder, the choice of motor is crucial. This paper will focus on the application of 45 kW DC motor (Brushed DC Motor) in extruders, discussing their working principle, advantages and performance in practical applications.

The working principle of 45 kW DC motor (Brushed DC Motor) is based on electromagnetic induction. When current passes through the motor's coil, a magnetic field is generated around the coil, which interacts with the magnetic field generated by the stator, causing the rotor to rotate. The brushes work in conjunction with the commutator to allow the direction of the current to change with the rotation of the rotor, thus maintaining a constant rotation of the rotor.

In extruders, 45 kW DC motor (Brushed DC Motor) is typically used to drive the screw rotation, which in turn drives the extrusion of material. 45 kW DC motor (Brushed DC Motor) is ideal for extruders due to their ability to provide high starting torque and good speed control.
