Product Description:
Okuma is a Japan based manufacturer known for CNC machines, drives and motion systems. It designs and produces high precision components for industrial automation. The company delivers advanced mechanical and electrical solutions with consistent quality and long term performance support. It serves global manufacturing needs with reliable engineering and service.
The VAC-MF15/11R-153 Servo Motor is a robust and compact unit designed for CNC applications. It offers two power ratings—15 kW for 30 minute operation and 11 kW for continuous operation. The rated voltage for this motor is 170 V in both modes. Current draw is 68 A for 30 minute use and 57 A for continuous use. This servo motor operates at variable speeds supporting 1500 rpm to a maximum of 6000 rpm. This motor's insulation class is rated F that allows it to operate in environments up to 155 °C. It uses deep groove ball bearings—6310ZZ at the drive end and 6210ZZ at the opposite end. Both are double shielded types to reduce dust ingress and wear. The terminal box is located on the top housing of this motor. It offers easy access for installation and maintenance. All connectors and wiring are clearly marked for proper integration. The protective components inside the terminal box prevent overheating and electrical faults.
The VAC-MF15/11R-153 servo motor weighs 133 kg and is suitable for high load setups. It features an enclosed frame that includes an integrated fan cooling system to ensure controlled internal temperature. This motor’s shaft is spline toothed that is designed for strong coupling with high torque loads like machine axes or CNC spindles. The structure is flange mounted which enables stable rigid installation onto machines. The mechanical build ensures reduced vibration and smooth operation under various loads.
