Product Description

The drive, motion control, and factory automation products designed by Okuma share a quality of unrivaled durability. Okuma is a top Japan-based designer of such products, many of which have many industrial applications. It has decades’ experience and has produced equipment like grinders, machining centers, lathes, CNC machine tools, and CNC controls. The VAC is a series of spindle servo motors designed and manufactured by the company.

The VAC-MFL3.7-2.2R-151-R4 is a model of the spindle servo motors in the VAC series designed by Okuma. Its speed range is between 1,500 revolutions per minute and 8,000 revolutions per minute. It has a continuous power output rating of 2.2kW and a peak power rating of 3.7kW. It demands a connecting voltage of 130V for its operation and a continuous current of 21A. The peak current rating of the spindle servo motor is 27A. Its drive end has a bearing code given as 6307ZZ, while it is given as 6206ZZ on the opposite end.

Based on the specifications given by NEMA, the VAC-MFL3.7-2.2R-151-R4 is a product of insulation class F. This is why the maximum possible temperature of its winding insulation is 155^oC. The motor also demands an ambient temperature that ranges from 0^oC to 40^oC for its continued optimal operation. It should be protected from potentially harmful chips, water, and oil to extend its lifespan. The drive unit of this VAC motor model is a VAC drive unit. One of the most important features of the drive unit is its LEDs that provide information on the operating status of the motor.
