M4000 Brush Motors

M4000
M4000  Series DC  Brush  Servomotor

High performance DC Brush Servo Motors

M4000 ( 4 inches diameter) is a member of Mechatronic's family of DC brush servomotors.  Series M4000 utilizes high energy rare earth magnets and designed for tough industrial and military applications. M4000 features compact size, high power density, with 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 M4000 is the solution for aftermarket field replacement
of virtually all brands of product. For new applications M4000 offers high Torque- to- Inertia and Torque-to- Weight ratios than ceramic or samarium cobalt based magnet design.
Low cogging is achieved by skewed laminations. This  design provides smooth rotation at near zero speeds.

M4000 is  made in the USA at our Boston factory.  This allows  Mechatronics Systems to respond very quickly to customer's need whether it is a one piece prototype or a five hundred pieced order.
Motors can be customized to fit your exact need with tachometers, encoders, resolvers, brakes and gearboxes.

Over the last 10 years a large number of  M4000 servomotors have been installed in CNC machine tools, paper, plastic, radar and antennas, textile, packaging as well as military applications
