Direct Drive DC Torque Motors

The Direct Drive DC torque motor is a servo actuator which can be directly attached to the load it drives. It has a permanent magnet (PM) field and a wound armature which act together to convert electrical power to torque. This torque can then be utilized in positioning or speed control systems. In general, torque motors are deigned for three different types of operation: · High stall torque ("stand-still" operation) for positioning systems · High torque at low speeds for speed control systems, and · Optimum torque at high speed for positioning, rate, or tensioning systems. Direct drive torque motors are particularly suited for servo system applications where it is desirable to minimize size, weight, power and response time, and to maximize rate and position accuracies. Frameless motors range from 28.7mm (1.13in) OD weighing 1.4 ounces (.0875 lbs) to a 4067 N-m (3000 lb-ft) unit with a 1067mm (42in) OD and a 660.4mm (26in) open bore ID. Housed motors range from a one inch cube design with 0.049 N-m (7 oz-in) peak torque to any of the frameless motors housed to customer specifications with integral DC tachometers, resolvers, encoders and shaft configurations.

INTRODUCTION

Advantages of Direct Drive DC Torque Motors
High Torque-to-Inertia Ratio at the Load A direct drive motor provides the highest practical torqueto-inertia ratio where it counts--at the load. In a geared system, reflected output torque is proportional to the gear reduction while reflected output inertia is proportional to the square of the gear reduction. Thus, the torque-to-inertia ratio in a geared system is less than that of a direct drive system by a factor equal to the gear-train ratio. The higher torque-to-inertia ratio of direct drive motors makes them ideally suited for high acceleration applications with rapid starts and stops. High Torque-to-Power Ratio Most torque motors are designed with a large number of
