Structure of a Coreless Motor
Coreless motors are a type of electric motor that, as the name suggests, do not have an iron core in the rotor. Instead, the rotor is made up of a wire winding shaped like a cylinder or basket around the motor shaft. This design results in several performance benefits compared to traditional motors with an iron core in the rotor. Here's a detailed breakdown of the structure of a coreless motor.
1. Rotor (Armature)
> The rotor in a coreless motor is made up of a winding of copper wire that is shaped into a cylinder or basket without a core. This is what makes the motor "coreless."
> Because there is no iron core, the rotor has very low inertia, which allows it to accelerate, decelerate, and reverse direction quickly.
> The winding is often supported by a non-magnetic material that provides the structural integrity of the rotor.
2. Brushes
> Coreless brushed DC motors use brushes and a commutator to transfer electrical current to the rotor winding.
> The brushes are typically made of carbon or graphite and make sliding contact with the commutator, which rotates with the rotor.
3. Commutator
> The commutator is a split ring that's attached to the rotor and works with the brushes to switch the direction of the current in the windings as the motor turns, ensuring continuous rotation.
4. Stator
> The stator provides the stationary magnetic field against which the rotor spins. It can consist of permanent magnets or electromagnetic windings.
> In the case of permanent magnets, they are usually arranged around the rotor to provide a consistent magnetic field.
5. Bearings
> Bearings support the rotating shaft and allow it to turn smoothly with minimal friction.
6. Housing
> The motor components are contained within a housing that protects them from environmental factors and also helps to dissipate heat generated during operation.
Classification of Hollow Cup motor
The hollow cup motor is divided into two types: brush and brushless. The rotor of the brush hollow cup motor has no iron core, and the stator of the brushless hollow cup motor has no iron core.
Why Use a Coreless Motor?
Since the 1930s, there has been a coreless or moving coil motor.
In the 1960s, advances in manufacturing made them practical and cost effective.
> There is no cogging torque.
> Controlling position and speed with ease
> High effectiveness
> Noise Reduction
> Extreme torque
> Low weight and rotor inertia
> Dynamic start-up and shutdown
Coreless Motor Advantages
Application of hollow cup motor
Because the hollow cup motor overcomes the insurmountable technical obstacles of the iron core motor, and its outstanding characteristics focus on the main performance of the motor, it has a broad application field. Especially with the rapid development of industrial technology, higher expectations and requirements are constantly put forward for the servo characteristics of the motor, so that the hollow cup motor has an irreplaceable position in many applications.
After the application of hollow cup motor has entered the large industrial and civil fields from the military and high-tech fields, it has developed rapidly in the past ten years, especially in the industrial developed countries, which has involved most industries and many products.
1. Servo system requiring fast response. Such as rapid adjustment of missile flight direction, follow-up control of high magnification optical drive, rapid automatic focusing, highly sensitive recording and detection equipment, industrial robot, bionic prosthesis, etc., hollow cup motor can well meet its technical requirements.
2. Products requiring stable and lasting driving of driving elements. For example, for all kinds of portable instruments and meters, personal portable equipment, field operation instruments and equipment, electric vehicles, the power supply time of the same group of power supply can be more than doubled.
3. Various aircraft, including aviation, aerospace, model aircraft, etc. Using the advantages of light weight, small volume and low energy consumption of hollow cup motor, the weight of aircraft can be reduced to the greatest extent.
4. All kinds of civil electrical appliances and industrial products. Using the hollow cup motor as the actuator can improve the product grade and superior performance.
5. Taking advantage of its high energy conversion efficiency, it is also used as a generator. Using its linear operation characteristics, it is also used as a tachogenerator; Equipped with reducer, it can also be used as torque motor.
With the progress of industrial technology, the strict technical conditions of various electromechanical equipment put forward higher and higher technical requirements for servo motor. At the same time, the application scope of hollow cup motor has completely separated from the limitations of high-end products, and is rapidly expanding its application scope in low-end products such as general civil products, so as to widely improve product quality. According to relevant statistics, hollow cup motors have been mature and applied to more than 100 civil products in industrial developed countries.
