Motion Control Products (MCP) is excited to introduce a range of high quality, high precision slotless BLDC motors for fast movements and a robust power delivery motion system.
In contrast to traditional slotted BLDC motors, slotless BLDC motors take a different approach in the motor design: Instead of winding copper wire through lamination slots, it is wound into a cylindrical shape, offering enhanced protection and rigidity. This slotless configuration overcomes the problems of air gap magnetic induction pulsating issues. This phenomenon is typically caused by irregular magnetic resistance in toothed motors, resulting in undesirable vibrations and inefficiencies.
In a slotless BLDC motor, copper wire is wound into a cylindrical shape and protected, rather than being wound through lamination slots as in conventional slotted BLDC motors. This design eliminates the need for a slotted stator lamination stack, ultimately reducing cogging, vibration, and noise. Additionally, the rotor can have a larger diameter, which therefore increases the torque.
The absence of teeth in a slotless motor reduces winding inductance and decreases damping for faster motor response. This results in less electromagnetic interference, making slot less motors suitable for high-speed and fast acceleration and deceleration applications.
As DINGS' Motion official UK business partner, Motion Control Products offers a diverse range of slotless BLDC motors, available in multiple sizes to cater to various dimensional requirements. The motor diameters are available in 10mm, 16mm, 22mm, 28mm, 36mm and 42mm.
Even smaller-sized motors can achieve impressive performance, voltages from 12V to 48V, 1 or 2 pole pairs, with powers of up to 200 watts, and a maximum loaded speed of 50,000 RPM and up to 91% motor efficiency. Motion Control Products' range of slotless brushless DC motors is tailor-made for servo systems that demand fast movements and robust power delivery.
Typical applications for a slotless BLDC motor include high-speed drilling, medical devices such as angioplasty equipment, medical imaging equipment, scanners, miniature pumps, testing equipment, measuring equipment, laser beam reflector rotation, fluid dispensing in medical pumps and aircraft control systems.
