Brushless DC Motor Series 57BLY
The 57BLY Brushless DC motor is a synchronous electric motor which is powered by direct-current electricity (DC) and which has an electronically controlled commutation system, instead of a mechanical commutation system based on brushes. In such 100w bldc motors, current and torque, voltage and rpm are linearly.

Technical performance advantages
High energy efficiency and energy saving
The energy efficiency of 100W BLDC motor can reach more than 90% (traditional brushed motors are usually 70-80%), reducing energy waste and complying with the global trend of energy conservation and emission reduction (such as EU ErP directive and US DOE standard).
Long life and low maintenance
The brushless design eliminates mechanical friction, extending the life by 3-5 times that of traditional motors, reducing downtime maintenance costs.
100w bldc motor is suitable for harsh environments (such as high temperature, high humidity, and dust), such as agricultural machinery, outdoor drones, etc., to meet the stringent reliability requirements of international customers.
Precise control and high dynamic response
Supports PWM speed regulation and closed-loop feedback (such as encoder integration), with a speed control accuracy of ±1 RPM, suitable for applications that require precise operation (such as medical equipment, automated robotic arms).
Sunrise Electric Motor provides customized control algorithms to adapt to voltage standards in different countries (such as 220V/50Hz or 110V/60Hz).
