What is considered a large BLDC motor?

A large BLDC motor typically means a brushless DC motor rated 1kW or higher, with frame sizes from 100mm to 130mm and supply voltage of 48V, 72V or 96V. They are used in heavy AGV, logistics vehicles, industrial mixers, solar trackers and material handling — applications where continuous power above 1kW is required.

Why use BLDC instead of induction motors at 1kW+?

BLDC motors at 1kW+ deliver higher efficiency (85-92% typical) than induction motors, lower heat dissipation, easier closed-loop control and broader speed range without external VFD complexity. The cost premium is offset by smaller battery requirements in AGV / logistics applications and lower energy bills in industrial drives.

What voltage is best for high-power BLDC motors?

48V is the most common for 1-1.5kW continuous BLDC. 72V is preferred for 1.5-2.5kW with longer cable runs and lower current draw. 96V is used in heavy AGV traction and pallet-truck AGV above 2.5kW. Higher voltage reduces I²R losses, simplifies wiring and improves thermal margin.

Do large BLDC motors need a gearbox?

Most heavy AGV, logistics and industrial-drive applications use a gearbox to convert the motor's 2500-3500 RPM into a usable wheel or output speed. Planetary gearboxes are preferred for high torque density and compact size. Right-angle gearboxes are chosen when 90-degree transmission or space matters more.

Brake required on large BLDC motors?

Yes for any large BLDC motor that must hold position on a slope, must stop within a defined distance during emergency stop, or remain stationary under load — pallet AGV, logistics vehicles, lifting equipment. An electromagnetic holding brake adds 20-40mm to motor length and is sized to the motor torque.

What information should I send for a large BLDC motor quote?

Send target voltage, continuous power, peak power, output speed, required torque, gear ratio (if any), shaft type, mounting, encoder / brake / controller need, duty cycle, ambient temperature, and application context (heavy AGV / logistics / industrial). Quote in 24 hours.

Why Large BLDC Beats Induction At 1kW+

Higher Efficiency, Easier Control, Smaller Battery.

At the 1kW continuous power point, BLDC motors typically deliver 85-92% efficiency vs 75-85% for equivalent induction motors. That's smaller battery in AGV / logistics, less heat in industrial enclosures and easier closed-loop control without external VFD complexity. The cost premium pays back through energy bills and battery sizing.

Higher continuous efficiency than induction at the same frame
Lower heat — better thermal margin in AGV / logistics enclosures
Built-in or external controller for closed-loop torque/speed
Optional encoder and brake for autonomous applications
