Product Description:
The AKM44E-BKMNR-00 servo motor is manufactured by Kollmorgen within the AKM Synchronous Servo Motors series. As a permanent-magnet synchronous unit, it converts drive current from a matched amplifier into controlled mechanical torque for positioning axes, pick-and-place heads, indexing tables, and other motion elements in industrial automation. The model belongs to the company’s medium-frame line, giving machine builders a compact yet capable drive element that integrates readily with widely used control platforms.
Its flange follows the NEMA pattern, which simplifies mounting with standard gearboxes and machine frames. The square frame width measures 84 mm, establishing the dimensions used for precise seating and alignment. Rotor position is sensed by a resolver with two poles. This electromagnetic transducer supplies analog sine-cosine signals to the drive for closed-loop commutation. The single-turn feedback provides absolute position over one mechanical revolution without batteries or optical disks, while its inductive design improves resistance to dust and oil. The resolver body fits the industry-standard Size 10/15/21 envelope, allowing the use of common shielded connector kits during installation.
Mechanical output is transmitted through an open keyway on the shaft, providing positive torque transfer to pulleys or couplings. The motor is supplied without a brake, so static holding torque must be provided by drive current or an external clamp when power is removed. The magnetic stack has index 4, balancing continuous torque capability with an axial length suitable for compact enclosures. The stator uses the E winding designation, which matches its electrical characteristics to the voltage levels expected from compatible Kollmorgen drives. The standard customization level includes cable exit, feedback, and mounting selections intended for common industrial motion-control installations.
