Product Description:

The VAC-MFE15/11R-153HS2 Servo Motor is the product of Okuma ensures long lasting and reliable performance in demanding industrial applications. This model belongs to the VAC Servo Motors series and is an ideal for CNC and machining centers where precision and power are critical.

The VAC-MFE15/11R-153HS2 servo motor is designed with integrated cooling methods such as fans or heat sinks to maintain optimal operating temperature. It is used in CNC machines or automation systems and is typically rated for continuous operation which means it can run without overheating or degradation under normal operating conditions for an extended period. This module has a rated speed of 1500 RPM which means it operates optimally at this speed under rated conditions. It is designed to work with either 50 Hz or 60 Hz electrical power supply, which is typical for industrial AC motors and can operate in regions with either frequency. It is able to sustain continuous operation at 11 kW of power without overheating which means it can provide thus much power during regular use over an extended period. When working continuously this model draws 69 amperes of current which means it is a larger and more powerful motor.

The VAC-MFE15/11R-153HS2 servo motor bearing is positioned at the drive end, which is where the load is connected that supports the motor’s rotor and ensures smooth rotation. It is designed to integrate directly into machinery, as opposed to being a standalone unit which is a common feature in industrial systems, where space optimization and ease of integration are important. It is designed to be highly efficient which means it converts a larger proportion of electrical energy into mechanical energy without any significant losses.
