VAC-YMM30/22R-082W
by Okuma
The Okuma VAC-YMM30/22R-082W servo motor is a high-performance solution in the VAC Servo Motors series designed to address demanding industrial automation requirements. This robust unit delivers dual power ratings of 30 kW for a 30-minute duty cycle and 22 kW for continuous duty cycle, operating at a nominal 170 V, ensuring flexibility across varied operational profiles. Engineered for integration with the Okuma LB25 machine model, the VAC-YMM30/22R-082W facilitates seamless compatibility and precision motion control in high-load applications. Manufactured by Okuma in Japan, the motor features a rugged mechanical design optimized for durability and long service life. Its substantial build, measuring 32 inches in length and 16 inches in width, and weighing 260 kg, underscores its industrial-grade robustness.
Technical specifications of the VAC-YMM30/22R-082W define its performance envelope with clarity. It requires a continuous voltage of 150 V and operates on 170 V (both ratings) for rated voltage consistency. Electrical draw is rated at 137 A for the 30 kW interval and 106 A for 22 kW continuous operation. The motor’s max speed of 6000 RPM and dual-RPM capability guarantee high-speed response. Bearing assemblies include a 6314ZZZ bearing at the drive end and a 6310MZZZ bearing at the opposite end to support stable, low-friction rotation. The built-in Drive unit D22A/1104 provides precise control, while insulation class F ensures reliable thermal performance. The unit is expressly compatible with the LB25 machine model, simplifying integration within Okuma’s equipment ecosystem.
Operational performance of the VAC-YMM30/22R-082W is tailored for demanding industrial environments. The motor employs a forced air-cooling system to maintain optimal thermal balance under full load. It supports an ambient operating temperature range of 0 °C to 40 °C, with storage capabilities from -20 °C to +60 °C, and sustains functionality in 30% to 90% relative humidity. Installation is certified for altitudes up to 1000 MSL, ensuring reliable performance at moderate elevations. Constructed in Japan with high-precision manufacturing processes, the motor’s mass and mounting provisions enable secure integration into heavy-duty machinery.
System integration of the VAC-YMM30/22R-082W is streamlined through its adherence to Okuma’s control protocols and mechanical interfaces. The motor’s compatibility with the D22A/1104 drive unit supports advanced feedback and tuning features essential for precision CNC and mill-turn operations. As part of the VAC Servo Motors series by Okuma, this unit targets applications in large-scale machining centers, high-speed milling, and automated assembly lines. Its balance of power density, environmental resilience, and seamless system integration positions it as an ideal choice for industrial automation professionals seeking dependable, high-performance motion solutions.
