Robot pet bldc motor

BL4820 has a multi-slot pole configuration of 20 poles and 24 slots with fractional slot design. This comes with the capability to optimize torque ripple and utilize concentrated windings to reduce motor resistance and improve efficiency.


Compact size:

The compact size allows for easy integration into the inside of wheels, enabling more refined and compact overall design of the machine.


Outer rotor structure:

The outer rotor design of the motor leads to a greater power density and output torque in a given volume.


Magnetic encoder utilization:

A magnetic encoder is used to control motor speed (accurately from 1 to 1000 RPM) and rotor angle position (360/1024), providing precise start-stop and position control.


Direct dirve motor technology:

The outer rotor direct drive reduces motor noise and improves overall compactness of the structure.


Improved speed range:

BL4820 has a significantly improved speed adjustment range compared to geared motors (from 1-80 RPM to 1-1000 RPM).
