Choosing a Servo - Direct Drive

IRON CORE OR CORELESS

Direct coupling, space savings, and smooth movement are important reasons to choose Yaskawa direct drive servo motors. Yaskawa’s SGM7D motors feature heavy-duty bearings and winding technology optimized for large mechanical loads. The SGM7F motors are very compact, and their iron-core design further improves torque density. The coreless design of the SGM7E eliminates motor cogging, ensuring smooth motion even at very low speeds. A direct drive product can be coupled directly to a load, eliminating gearboxes and couplings to reduce machine cost, eliminate maintenance headaches, and prevent mechanical breakdowns. Yaskawa’s direct drive designs are among the most compact in the automation industry, enabling more space-efficient machine designs.
