BMC3500 Low and Medium Inertia Brushless Servomotor
![M3000](/images/stories/products/m3000.jpg)
High-performance AC Brushless Servo Motor
The BMC3500 high-performance AC servomotor is a new addition to our family of motor products. The BMC3500 has one of the smallest footprints in the industry, featuring high-energy rare earth magnets and a high-efficiency magnetic and mechanical design. The motor is designed for tough industrial servo applications. The BML3500 has low inertia for new high-speed machine designs. The BMM3500 differs only by having higher inertia, which is often required for the stable operation of older machines and position controllers. The BML/M is designed with a variety of custom configurations to address the needs of new applications as well as aftermarket support. Because the BM series is powerful and compact, it can be used as a direct Form, Fit, and Function replacement for many different motor brands, such as Ametek (MCG), Rockwell International, and Parker, to name a few.
BMC3500 motors are available with Mechatronic's Systems Servo Amplifiers, such as the BSA series. We often design custom servo amplifiers for cost-sensitive applications where only needed functions are implemented. Please contact our Application Engineering team for specific requirements.
All our products are made in the USA at our Boston factory. Mechatronics Systems is committed to providing a fast turnaround for our OEMs and end-user customers. Motors can be customized to fit your exact needs with tachometers, encoders, resolvers, brakes, and gearboxes.
