Product Description:

The DD045CB4ANEA100 linear servo motor coil is produced by Sanyo Denki for the Linear Servo Motors series. Designed for direct-drive positioning stages, the unit converts stator current into linear thrust without rotary transmissions, allowing compact and precise motion in pick-and-place gantries, packaging lines, and semiconductor equipment. Within a complete system, it works with a matched servo amplifier and encoder scale to translate digital commands into controlled force along the machine axis. The direct-drive arrangement eliminates mechanical transmission components that could introduce backlash, compliance, or additional friction during rapid positioning movements.

A servo amplifier rated for 75 A is required to deliver the peak phase current to the coil windings. When connected to the appropriate amplifier, the mover can reach a maximum travel velocity of 3.0 m/s, providing rapid indexing across long strokes. Continuous operation is supported at a rated velocity of 1.9 m/s, where copper losses are transferred through the mounting plate. Maximum instantaneous thrust reaches 2200 N for short acceleration periods, while steady-state operations such as contour cutting are supported by a rated thrust of 800 N. Load mass, acceleration, stroke length, and duty cycle must remain within these operating limits to prevent excessive thermal loading. The servo amplifier regulates winding current in response to position commands and feedback signals, allowing the axis to maintain controlled movement as the applied load changes.

The assembly weighs 8.6 kg and includes a 300 mm pigtail for routing power and sensor connections inside the machine. A magnetic attraction force of 600 N must be considered when selecting linear guide preload and mechanical safety stops. The recommended assembly height is 70 mm, and a bottom clearance of 7.5 mm provides space beneath the iron-core assembly. Eight M6 threaded holes, each 9 mm deep, secure the housing to the machine bed. Two 4 mm positioning bores with a +0.02 mm tolerance support repeatable alignment during installation. Without a cover, the right-side air gap is 0.7 mm, while installing the optional shield reduces the gap to 0.6 mm. A Hall sensor embedded in the coil supplies coarse commutation data to the drive before precise position feedback becomes available from the encoder scale.
