Custom BL80 series 80mm Diameter Brushless Dc Motor Factory, Manufacturers- Suzhou Retek Electric Technology Co., Ltd

The High-Density Torque Solution in 80mm Frame Size

The 80mm diameter BLDC motor is an optimized design for applications requiring exceptionally high torque in a slightly larger, often square-flange format, frequently overlapping with NEMA 32/34 power levels.

The BL80 series is engineered to be extremely power-dense, often utilizing a slightly longer stack length to achieve continuous outputs up to 1.5kW. This series often operates on higher voltage, typically 310VDC or 230VAC rectified, to maintain high efficiency and limit current. The construction emphasizes mechanical stiffness and robust terminal connections to handle the high electrical power and corresponding mechanical output forces. The 80mm size provides an excellent platform for integrating industrial-grade resolvers or absolute encoders for high-accuracy servo positioning.

Frequently Asked Questions

Common Inquiries Regarding BL80 Motors

Q: How does the BL80 series handle the high 310VDC bus voltage?
A: The motors are built with enhanced winding insulation (e.g., thicker enamel coating, insulating paper) and larger air gaps to ensure high dielectric strength and prevent internal arcing or shorts at high bus voltages.

Q: Is there a significant advantage to using a resolver over an encoder in this series?
A: Resolvers are mechanically robust, highly immune to electrical noise, and less sensitive to temperature extremes than many encoders, making them suitable for harsh industrial environments, particularly near high power switching equipment or intense heat sources.

Q: Can the BL80 motor be mounted in any orientation?
A: Yes, the use of sealed, pre-lubricated ball bearings ensures that the motor can be mounted horizontally, vertically, or at any angle without affecting bearing life or lubrication effectiveness.
