High Torque Automotive Electric BLDC Motor-W4241
his W57 series brushless DC motor(Dia. 57mm) applied rigid working circumstances in automotive control and commercial use application.
This size motor is very popular and friendly for users for its relative economic and compact comparing to big sized brushless motors and brushed motors.
Product introduction:
This product is a compact high efficient brushless DC motor, magnet ingredient consist of NdFeB(Neodymium Ferrum Boron) and high standard magnets imported from Japan which greatly enhance the efficiency comparing to others available motors in the market.Top quality bearing with strict end play greatly improve the precision performance.
Comparing to brushed dc motors, it has great advantages as below:
● High performance and efficiency - BLDCs are broadly more
efficient than their brushed counterparts. They use electronic
capabilities, allowing for fast and precise control of the speed
and position of a motor.
● Durability - There are fewer moving parts that control brushless
motors than PMDC, making them more resistant to wear and impact.
They're not prone to burnout due to sparking that brushed motors
often encounter, making their lifespan significantly better.
● Low noise - BLDC motors operate more quietly because they don't
have brushes that constantly make contact with other components.
