Product Description:
Part of the AKM2G series, the AKM21G-BNM22-00 servo motor is designed to satisfy the demanding requirements of high-performance industrial applications. Kollmorgen manufactures it. In dynamic automation systems, this synchronous servo motor incorporates cutting-edge design concepts to guarantee longevity, accuracy, and efficiency. With a maximum torque of 1.78 Nm and a maximum current of 8.66 A, the AKM21G-BNM22-00 continues to operate with remarkable steadiness. With its rated torque of 0.583 Nm, rated speed of 4800 rpm, and rated power output of 0.293 kW, it is appropriate for applications that need great responsiveness. As the winding temperature rises to 100°C, its continuous torque capacity reaches 0.636 Nm, and at 60°C, it reaches 0.494 Nm.
The motor can reach a mechanical speed of up to 8000 rpm and supports a maximum continuous current of 2.17 A, guaranteeing excellent performance under a variety of workloads. The electrical properties of the motor improve its dependability and efficiency. Stable electrical performance is facilitated by an inductance saturation current of 15 A and a winding resistance of 7.30 Ω. Its thermal resistance of 1.33 °C/W and thermal time constant of 9.6 minutes further promote efficient heat dissipation, extending lifespan. The motor's responsiveness and smooth operation are further improved by its viscous damping coefficient of 0.0015 Nm/krpm and static friction torque of 0.006 Nm.
With a rotor moment of inertia of 0.093 kgcm² and a weight of 1.1 kg, the AKM21G-BNM22-00 is a sturdy and compact structural device. It has three pole pairs and uses a resolver for feedback, which guarantees accurate motion and exact placement. It can sustain an axial load of up to 120 N and a maximum radial load of 42.8 N since it is made to handle mechanical stresses. The motor has a minimum cross-section of 1.5 mm² and a reference flange diameter of 58 mm. With a feedback derating of 98.2% at 1000 rpm and 96.0% at 2000 rpm, its efficiency is still good even at different speeds. The AKM21G-BNM22-00 is a great option for industrial automation because it strikes a balance between power, dependability, and affordability while providing reliable performance in a variety of operating situations.
