FAQs from the Product Perspective

(NEMA 34 / 86BLS Geared Brushless DC Motor)

1. What is a NEMA 34 geared brushless DC motor used for?
A NEMA 34 geared BLDC motor is used in high-torque industrial applications such as automation machinery, conveyors, AGVs, packaging equipment, CNC auxiliary axes, and robotic systems.

2. What are the advantages of a geared BLDC motor compared to a standard BLDC motor?
The gearbox increases output torque, improves load handling, reduces speed, and allows the motor to operate in its optimal efficiency range.

3. What does NEMA 34 (86BLS) mean?
NEMA 34 refers to an 86 × 86 mm mounting frame size, suitable for medium- to high-power industrial motion control applications.

4. What types of gearboxes are available for this motor?
The motor can be equipped with planetary or other precision gearboxes, depending on torque, backlash, and lifespan requirements.

5. How does the gearbox affect motor torque and speed?
The gearbox multiplies output torque while proportionally reducing output speed, making it ideal for heavy-load, low-speed applications.

6. Is the NEMA 34 geared BLDC motor suitable for continuous operation?
Yes, it is designed for continuous industrial operation with high efficiency and stable thermal performance.

7. Does the motor support Hall sensor feedback?
Yes, Hall sensors provide accurate commutation and stable speed control, especially under varying load conditions.
