Product Description:
The Japanese company Okuma produces VAC-MFL3.7/2.2R-151-R2 as Servo Motor. This product comes from the VAC Servo Motors Series that is aimed at precise CNC machinery operations and industrial automation. It enables short-term operation during 15-minute run times under 3.7 kW of power or continuous production at 2.2 kW.
This VAC-MFL3.7/2.2R-151-R2 servo motor delivers its continuous power rating at 2.2 kW. This supports speed operation ranges from 1500 to 8000 RPM. The motor runs on 130 V of supply voltage. It can draw 27 A of peak current from the system. The motor works at 21 A during continuous operation for maximum efficiency. The servo motor needs a standard three-phase AC connection, which defines its electrical needs for high-performance operation. Position feedback is possible through the included incremental encoder installed on the VAC-MFL3.7/2.2R-151-R2 servo motor. The position feedback accuracy of this encoder reaches 2500 pulses each time the system completes a revolution. The F insulation class offers a thermal limit of 155 °C for the circuitry. This motor technology is appropriate for industrial settings that require high thermal resistance. The motor achieves an IP55 protection ranking which defends it from dust entry and short water sprays. The motor possesses 33 kg weight because its construction materials serve heavy industrial applications.
The smooth operation of the VAC-MFL3.7/2.2R-151-R2 servo motor depends on bearings installed on both ends at the drive side (6307ZZ) and the opposite side (6206ZZ). The high-speed applications need these bearings because they serve as essential components for both maintenance activities and extended reliability. The designed operating temperature range of the motor extends from 0°C to 40°C. The motor functions during conditions with humidity reaching maximum levels of 85% while staying free from condensation effects. Internal cooling fans are included as standard components in VAC series motors to maintain optimal operating temperatures.
