M4000 High-performance DC Brush Servomotors
High-Performance DC Brush Servo Motors for Industrial and Military Applications
M4000, a 4-inch diameter DC brush servo motor, is a member of Mechatronics' family of high-performance servo motors. The M4000 series utilizes high-energy rare-earth magnets and is designed for tough industrial and military applications. It features a compact size, high power density, and delivers exceptional starting and continuous torque.
The use of rare-earth permanent magnets allows the M4000 servo motors to be significantly smaller than motors with ceramic magnets, offering the same power output. This makes the M4000 an ideal solution for aftermarket field replacements across virtually all motor brands. For new applications, the M4000 offers superior torque-to-inertia and torque-to-weight ratios compared to ceramic or samarium-cobalt-based magnet designs. Low cogging is achieved through skewed laminations, ensuring smooth rotation at near-zero speeds.
Over the past 10 years, a significant number of M4000 servomotors have been successfully installed in various industries, including CNC machine tools, paper, plastic, radar and antenna systems, textile manufacturing, packaging, and military applications.
