Less is more: new Frameless BLDC motors

DELTA LINE, a leading manufacturer of motion control solutions, is expanding its offering with the launch of frameless BLDC (brushless DC) motors, ideal for space-constrained applications that require high torque density and stiffness.

The frameless BLDC motors, manufactured by our company Fulling Motor, are available in sizes 50, 70, and 85, specifying the motor outer diameter in millimeters. With the frameless design, the motor’s rotor and stator can be integrated directly into the machine, providing significant space savings without sacrificing performance.

Frameless BLDC motors have proven to be an ideal choice for robotic applications, such as cobots and AGVs, where they can be directly integrated into the robot joint or AGV drive. This allows an overall space reduction while still providing high output torque. And the reduced weight and inertia of DELTA LINE’s frameless BLDC motors are important for applications in the robotic and automation fields, which require dynamic movements with high acceleration and deceleration rates.

Applications in the medical industry also benefit from the design and performance of DELTA LINE’s frameless BLDC motors. For example, noise and heat are significant concerns for medical devices that come directly into contact with the patient. To address these demands, DELTA LINE’s BLDC motors have been designed for low noise production and high efficiency, so heat generation is kept to a minimum. And high pole counts provide extremely smooth motion for applications where precision is critical, such as surgical tools.

Even small consumer appliances and handheld power tools can take advantage of the features of frameless BLDC motors – extremely compact dimensions, direct integration, high efficiency, and low noise. With DELTA LINE’s frameless BLDC motors, devices can be made smaller, more powerful, more efficient, and more user-friendly.

For precise, dynamic motor control, the size 50 and 70 frameless BLDC motors can be integrated with DELTA LINE’s Gemini controller. And our in-house engineering team can work with you to customize any of our motors to meet specific application, footprint, or performance requirements, so you get more – more performance, more space-saving, and mor precision – for less.
