What is the rated torque of a 400W BLDC motor?

Approximately 1.27 Nm at 3000 RPM rated speed. With a planetary or worm gearbox the output torque reaches 10-120 Nm.

What voltage should I pick for a 400W BLDC motor?

48V is the most common choice — it keeps the current under 10A for easier cable and controller sizing. 72V is available for applications with long cable runs or high bus voltage.

Which frame size is typical for 400W?

80mm and 86mm square frames are standard. 86mm provides more thermal headroom and larger bearings for 24/7 conveyor duty.

Is a matching controller included?

Yes. BLD22010 handles 48V up to 10A. For higher bus voltage, BLD6010 covers 80-220V with 10A, both validated as a pair with the motor.

400W Brushless DC Motor

400W BLDC Motor For Heavy Conveyor, Sortation And AGV Duty.

400W is the sweet spot for heavy conveyor, sortation diverter and AGV main drive duty — powerful enough to handle full-load acceleration, small enough to fit inside the machine frame. Shenghe builds the 400W BLDC in 80mm and 86mm frames, 48V and 72V, paired with BLD-series closed-loop drivers.

48V / 72V DC standard
80mm or 86mm frame
3000 RPM rated, ~1.27 Nm motor torque
IP54 standard, IP65 optional
