Product Description:

Kollmorgen manufactures the AKM22E-BNBNR-00. Compact and very versatile, the AKM22E-BNBNR-00 synchronous servo motor is designed to handle a variety of electrical input circumstances while preserving accurate torque and speed control. Starting at 0.22 kW with a 75VDC supply, its rated power output is voltage-dependent and increases to 0.3 kW at 115VAC. Operating the motor with a 230VAC input allows it to attain its maximum continuous output of 0.59 kW. For systems that need power scaling while preserving electrical efficiency and thermal stability, this voltage-responsive performance is essential. The motor can reliably provide this output at its rated speed and torque without exceeding thermal restrictions since its rated power is determined under continuous running circumstances. Because of this, it is especially well-suited for continuous-duty industrial applications where reliable mechanical output, even under extended workloads, is crucial.

The AKM22E-BNBNR-00 offers accurate torque characteristics that are tuned for both static and transient circumstances when looking at dynamic performance. The motor can withstand external disturbances and retain positional precision even when it is at a halt because of its holding torque of 0.87 Nm. The motor can produce up to 2.76 Nm of peak torque in transient or load-varying situations, allowing for quick overload management and quick acceleration. With a rating of 0.32 Nm per ampere, the torque constant measures the torque generated for each unit of applied current and establishes a direct connection between electrical input and mechanical output. In applications like robotic arms or pick-and-place systems that require precise force control, this electromechanical conversion efficiency is essential. Consistent actuation under varying load profiles is facilitated by the accurate connection between current and torque production, which also makes sophisticated control algorithms possible.

The motor's quick response to control signals is largely due to its low rotor inertia of 0.16 kg·cm². Faster angular acceleration and deceleration are made possible by this decreased moment of inertia, which also minimizes delay during speed ramps and direction changes. Consequently, it facilitates high-cycle-rate operations with low latency, which is especially useful in high-precision automation systems where responsiveness and timing are strictly regulated. When thrust forces apply along the shaft's axis, the motor's mechanical design ensures structural robustness by handling an axial shaft load of 60 N. By preventing excessive wear on internal bearings, this feature improves the motor's mechanical durability in a variety of mounting arrangements or couplings. With a rated speed that varies from 2500 min⁻¹ at 75VDC to 8000 min⁻¹ at 230VAC, the device may be used in applications with different speed requirements. Its range of appropriate industrial applications is further expanded by the multi-voltage operability, which facilitates integration into systems across several regional power standards.
