BM3500 Low and Medium Inertia Brushless Servomotor

M3000
BML 3500 Low Inertia Brushless Servomotor

High performance AC Brushless  Servo Motor

BM3500  high performance AC servomotor is a new addition to our family of motor products.   BM3500  has one of the smallest footprint in the industry featuring  high energy rare earth magnets and high efficiency magnetic and mechanical design.  The motor is designed for tough industrial servo applications.  BML3500 has low inertia for new high speed machine designs. BMM3500  differs only by having
higher inertia often required for stable operation of older machine and position controllers. BML/M is designed with variety of custom configuration to address the needs of new applications as well as
aftermarket support.  Being powerful and compact, BM series can be used as direct Fit Form replacement for many different motor brands such as  Ametek( MCG), Rockwell International and Parker
to name a few.

BM3500 motors are available with Mechatronic's Systems Servo Amplifiers, such as BSA series.  We often design custom servo amplifiers for cost sensitive applications where only needed functions are
implemented. Please contact our Application Engineering for specific requirements.

All our products are made in USA at our Boston factory. Mechatronics System is committed to to provide fast turnaround for our OEMs and Enduser customers. Motors can be customized to fit your exact needs with tachometers, encoders, resolvers, brakes and gearboxes.
