M3000 Brush Motors

M3000
M3000  series DC  Brush Motor

High performance DC Brush Servo Motor

M3000 (3 inches diameter) is a line of DC brush servomotors. M3000 utilizes high energy rare earth magnets and designed for tough industrial and military applications. M3000 features compact size, power density and
high starting and continuous torque.

The use of rare earth permanent magnets allow the motors to be much smaller than motors with ceramic magnets for the same power. Thus M3000 works very well as aftermarket field replacement
of virtually every brand of servomotors. If you are an OEM or a large end users looking to support the field, M3000 is the solution. For new applications M3000 offers High Torque-to-Inertia and torque-to- weight ratios than ceramic or samarium cobalt designs.  Low cogging is achieved by skewed lamination design which provides smooth rotation at near zero speeds.

M3000 motors are  made in the USA at our Boston plant. Motors can be customized to fit your exact needs with tachometers, encoders, resolvers, brakes and gearboxes. Mechatronics Systems  is committed to to provide fast turnaround whether you need one  piece or a thousand.

A large number of M3000 servomotors  have been installed in CNC machine tools, paper, plastic, radar and antennas, textile, packaging as well as military applications
