KG-08P0816R 8mm Diameter 10mm Length 3V Coreless Gear Motor

Coreless DC gear motor is made up two parts, precision gearboxs and a coreless dc motor.
Coreless DC gear motor is a type of coreless motor that does not have a winding around a central core. The stator of a coreless DC motor typically consists of two permanent magnets that are mounted on opposite sides of the motor. The rotor of a coreless DC gear motor typically consists of a permanent magnet that is mounted on a shaft.

What are advantages of coreless gear motors: Coreless DC motor doesn’t have a winding around a central core, which means that it can be more efficient than a traditional DC motor. Brush motors also tend to be smaller and lighter than traditional DC motors.

     Coreless brushed motors function similarly to traditional or cored brushed motors. With a coreless design, magnetic fields are induced by applying current and voltage to the rotor windings, which react with the  permanent magnet on the stator to convert electrical energy into mechanical energy. A coreless dc motor is typically constructed with rare earth magnets to maximize performance and mechanical strength from such a small form factor. An electric micro motor like this needs the best materials in order to have a high starting torque and rapid mechanical time constant.

     The removal of the iron core, within the housing cylinder, leads to other advantages as well. Armature Windings dissipate heat more efficiently without an iron core holding onto the heat in the middle of the motor. This improved thermal performance allows a coreless dc motor to to radiate its heat through the casing, removing the need for air holes of active cooling.  In turn the sealed casings help to reduce both audible noise as well as electrical noise or EMI, making coreless motor well suited for applications sensitive to electromagnetic interference.

  Coreless Motor Performance Curves

  A coreless motor's performance and gearbox performance are combined into one graph by displaying three specific parameters. These three parameters are speed, torque and efficiency. These performance curves are essential when selecting a motor for your application.

  

   

• Speed/Revolutions (N) – (unit: rpm) indicated as a straight line that shows the relationship between the motor’s torque and speed. It should be used near its peak efficiency to maximize the motor’s potential.

• Efficiency (η) – (unit: %) is calculated by the input and output values, represented by the dashed line. To maximize the motor’s potential it should be used near its peak efficiency.

• Torque (T) – (unit: gf-cm) this is the load borne by the motor shaft, represented on the X-axis.

• Current (I) – (unit: A) indicated by a straight line, from no load to full motor lock. This shows the relationship between amperage and torque.

• Output (P) – (unit: W) is the amount of mechanical energy the motor puts out.

Micro DC Coreless Gear Motor Structure

3V coreless motor is a high-speed, high-torque motor that is perfect for a wide range of applications. It features a high power density and low inertia, making it ideal for use in applications where space is limited. Additionally, the coreless design of this motor eliminates cogging and provides for smoother operation.
