M4-200X Brushed Motors

The M4-200X range of compact brushed servo motors has been designed specifically for robotics, machine tools and automatic handling equipment as well as for mobile and general servo-drive applications where accuracy, reliability and high power/ weight ratio are vitally important.

The use of rare earth magnets results in a compact motor with a very favourable power/weight ratio compared with conventional ferrite magnet or wound field motors. The maximum terminal voltage is 90 V, but very useful performance can be obtained from lower voltages, such as 48 or 60 V, with torque being maintained at reduced speeds.

The M4-200x brushed motors have provision for mounting tachos, encoders, resolvers and other positional feed-back devices using a spigot and a shaft extension at the non-driving end. A fail-safe brake can also be incorporated, as can alternative power connections by MS connectors, cable, or flying leads.

The Electrical Specification above is a sample of the standard windings available. There are many special windings designed to cover most speed/torque applications. If the windings below do not suit your application just contact us and we will find the right winding for you.
