What voltage options are available for 100W brushless DC motors?

Shenghe 100W BLDC motors are available in 24V and 48V DC as standard. 12V and 36V variants can be wound on order.

What frame size is typical for a 100W BLDC motor?

42mm and 57mm are the most common frame sizes for 100W. 42mm suits compact robotics and medical pumps; 57mm handles higher continuous duty with larger bearing life margin.

What is the rated speed of a 100W brushless DC motor?

Direct-drive rated speed is typically 3000 RPM. With planetary gearbox, output speed drops to 30-600 RPM depending on ratio.

Can I get a matching controller for the 100W motor?

Yes. Shenghe BLD22010 handles 18-60V up to 10A and pairs directly with the 24V and 48V 100W motor range.
