Direct Drive Servomotors

Direct Drive technology has recently become more and more commonplace in machine and factory automation. Parker‘s Electromechanical Division has been well known for many years as a specialist in direct drive technology. Parker offers various kinds of torque motor, in „ready to run“ and kit form, as well as linear motors. These motors are ideal for solutions in printing machines, bending machines or machine tools which require extremely smooth rotation, especially at very low speed, and very high accuracy. Frequently there is also a requirement for a hollow shaft.Designed with the aim of addressing new industrial needs, Parker has developed the ST range of low inertia motors for Direct Drive providing acceleration rates up to 20 000rad/s². The ST range is available in three diameters, 145mm, 190mm and 300mm, with either hollow or solid shafts of 60mm till 75mm diameter respectively. Rated torques range from 15Nm to 235Nm in natural convection, with peak torques from 55Nm to 1161Nm. The motors can reach rated speeds of 200pm till 1 500rpm according to winding type and provide exceptional speed regulation at low speed.The 145mm, 190mm and 300mm ST ranges offer outstanding performance with a continuous torque-to-weight ratio up to 3.7Nm/kg and a peak torque- to-weight ratio up to18Nm/kg. Parker has also expanded its product portfolio with a new range of Direct Drive frameless motors. Complementary to its ST range, these kit motors (stator + rotor) are designed to be integrated within machine tools such as rotary tables and grinding heads. These applications frequently require a large-diameter hollow shaft as well as high accuracy and speed regulation. The new STK frameless motor range offers outstanding rated torque from 15Nm to 2 700Nm in natural convection, and can reach 6 100Nm using fluid cooling. The peak torque is 3 times higher than the rated torque (up to 9 000Nm) and is available up to the rated speed.The large-diameter hollow shaft provides an internal clearance between 56mm and 630mm. Parker Direct Drive motors have been designed and industrialised with the aim of ensuring excellent performance as well as acceptable cost for users.

Direct drive is more than just a good idea!
