Product Description:
As one of Okuma product lines, the VAC-MML7.5/5.5R-155 Servo Motor is built to provide high-current motor technology. The innovations from Okuma remain reliable and perform with high efficiency while simplifying complex operations to become more effective.
This VAC-MML7.5/5.5R-155 servo motor showcases a high voltage requirement of 150 volts and helps the motor to power up by starting its functions. Its highest energy output is indicated by its 3.5 kW power classification to enable greater load carrying and faster functioning by demonstrating the ability to do mechanical work efficiently. The VAC series servo motor can adapt to changing operational specifications and increase its capacity to process at 1500 revolutions per minute (RPM) under persistent load and up to 8000 RPM for brief bursts. The initial electrical current surge needed to start the motor is indicated by the current rating of 44 A at 0 minutes during uninterrupted operation, this value decreases to 37 A. Determining the required electrical circuit capacity and preventing overloading depend heavily on these parameters. The motor can run safely at temperatures up to 155°C due to insulation Class F which assists in increasing temperature tolerance.
The VAC-MML7.5/5.5R-155 servo motor’s bearings promote finer rotation and lowered wear over time by reducing friction between moving components. By avoiding excessive heat buildup by decreasing maintenance requirements and prolonging the motor's life, the 608ZZ bearing on the driving end and the 620872 offer longevity and reliable activities. Its accessibility and the installation's structural needs are significantly influenced by the bulky 69 kg weight. Also, heavier motors are generally more stable and durable but, in some situations, their weight may affect the logistics of installation and transportation.
