Servo Voltage Stabilizers for CNC Machines
Unstable voltage is a common issue in industrial environments and can severely affect sensitive equipment like CNC machines. To address this problem, Purevolt offers high-performance Servo Voltage Stabilizers that deliver a stable and balanced output supply, even during voltage fluctuations or unbalanced conditions. These stabilizers are specially designed to protect the delicate electronic circuits and control systems used in CNC machines.
CNC machines typically operate on the following power systems:
-
3-phase, 4-wire grounded service from 208Y/120V to 480Y/277V
-
3-phase ungrounded service at 480V delta or 240V delta
Voltage fluctuation is one of the main causes of CNC machine malfunction. Since CNC systems rely on precise electronic controls, even minor voltage disturbances or stray electrical noise can disrupt operations.
Our Servo Stabilizers are compatible with leading global CNC machine manufacturers such as:
-
Hitachi – Operating in India since the 1930s, known for high-quality CNC machines.
-
Makino – Renowned for premium CNC machines, with offices in Bangalore, Delhi, Pune, and Mumbai.
-
Yasda – Manufactures premium CNC machines built to international standards.
-
Yamazaki Mazak – One of the top CNC machine manufacturers in India and worldwide.
-
Mori Seiki – Globally recognized for advanced machine tools and CNC systems.
Proper grounding is essential for CNC machines to function correctly. The signal reference in a CNC machine is connected to the machine’s ground plate, which is bonded to the enclosure and further connected to the building grounding system. Although CNC cabinets are well shielded, differences in ground reference points across a factory can increase sensitivity to power disturbances, leading to malfunction. A Servo Voltage Stabilizer helps eliminate such risks by maintaining consistent voltage levels.
