Product Description

Okuma is a leading manufacturer and designer of motion control equipment and accessories used in industrial automation purposes, specifically motion control devices. The company offers a wide range of drive units, CNC machines, spindle motors, and servo amplifiers.

The VAC-MML7.5-5.5R-156C model is a spindle motor and a significant part of the Okuma drive system. Okuma VAC spindle motors use radial bearings that are specifically engineered to work at higher velocity and with extreme resolution than standard electric motor bearings. Before being manufactured, all spindle motors are dynamically balanced. Equilibrium is an important part of every spindle motor rebuild. To achieve the intended longevity, this motor must be constructed to Okuma's tight dimensional tolerances. Your VAC spindle motor will be run through a break-in period to maximum speed, examined for high noise levels and heating, and vibration levels recorded once the assembly accuracy is assured. The spindle motor maintains its precision through a magnetic encoder or optical PG connector. A grounding terminal hole is provided for the power cable to pass and ground the housing of the electric motor. The motor may misbehave if the grounding is not done properly.

The model VAC-MML7.5-5.5R-156C is inspected and tested for smooth and safer operation. Use protective devices to prevent damage from electric current fluctuations and high voltages. Keep your drive system clean and regularly check if any component is near to jam. Jamming may cause the winding burn if no protective device is used. The model VAC-MML7.5-5.5R-156C includes a VAC card and VAC board, a power supply, and a door. All these components are covered with a metallic plate. Mounting holes are provided for hassle free installation. The spindle motor comes with a control signal cable connector and a push button switch. The motor is protected with 2 warning fuses to indicate any malfunction.
