Product Description:

The VAC-YMM30/22R-082W Servo Motor is manufactured by Okumaa global manufacturer in industrial automation and machinery solutions. This high-performance servo motor is designed for compatibility with the Okuma LB25 machine model. It offers two power ratings to suit different operational demands that is 30 kW for a 30-minute duty cycle and 22 kW for continuous duty.

The VAC-YMM30/22R-082W Servo Motor power levels operate at a rated voltage of 170 V that ensures efficient energy usage. The current draw is rated at 137 A for the 30-minute cycle and 106 A for continuous use that supports a stable and consistent motor function. This servo motor has features of strong mechanical construction with high-quality bearings for improved durability. It uses a 6314ZZZ bearing at the drive end and a 6310MZZZ bearing at the opposite end to support stable rotation. The motor achieves a maximum speed of 6000 RPM which makes it suitable for high-speed applications. It is equipped with a D22A / 1104 drive unit that guarantees smooth and precise control. With a continuous voltage rating of 150 V and insulation class F the motor is built to perform reliably under thermal and electrical stress. The total weight is 260 kg which allows for secure installation in industrial setups.

The VAC-YMM30/22R-082W Servo Motor has environmental specifications of the VAC Servo Motor support wide application use. The operating temperature ranges from 0 °C to 40 °C and storage conditions allow for -20 °C to +60 °C. The unit functions ideally in 30 - 90% humidity level. This module can be mounted at the altitude of 1000 MSL. The motor uses a forced air-cooling system to maintain optimal temperature during operation.

Frequently Asked Questions about VAC-YMM30/22R-082W:

Q: Why does the VAC-YMM30/22R-082W use forced air-cooling instead of passive cooling?

A: Forced air-cooling allows for better heat dissipation during high-speed operations, maintaining optimal motor temperature and prolonging component life.

Q: How does insulation class F benefit the VAC-YMM30/22R-082W motor?

A: Class F insulation can handle temperatures up to 155°C, enhancing the motor’s electrical durability in demanding industrial conditions.

Q: Why is a 150 V continuous voltage rating important for the VAC-YMM30/22R-082W Servo Motor?

A: It ensures stable voltage delivery under continuous load, which is critical for preventing voltage drops during extended machining cycles.

Q: What role do the 6314ZZZ and 6310MZZZ bearings play in the VAC-YMM30/22R-082W motor?

A: These bearings provide axial and radial stability, enabling smoother high-RPM operation and longer mechanical lifespan.

Q: Why is 6000 RPM significant for the VAC-YMM30/22R-082W Servo Motor?

A: This high rotational speed supports fast acceleration and responsiveness, making it suitable for precision CNC or robotics environments.
