This paper addresses the relationship between the weight of DC moving-coil permanent-magnet motors and the requirements for the driven motion. The requirements for motion are assumed to be made in terms of a maximum absolute velocity and a maximum absolute acceleration. A move consists of periods of maximum acceleration and periods of maximum velocity, so called trapezoidal velocity profiles. The load on the motor-drive-train is characterized by a maximum torque or force which is assumed to occur during a period of maximum acceleration. The DC motor is assumed to be limited by a maximum torque applied magnetically to the armature essentially a maximum current and by a maximum armature speed. Within these constraints simple procedures for identifying the lightest motors are given. An analysis of several series of popular motors is provided which defines the current state-of-the-art for such motors.
