WE CAN HANDLE ANY REPAIR CHALLENGE

Team of experts working at a modern and well-equipped facility

Our modern  and well-equipped facility provides us with all the necessary tools to evaluate and repair your AC or DC drive, from multi-meter and DC power supplies, to extensive soldering equipment and circuit analysis devices. Our large inventory of spare parts guarantees a quick turn-around on repairs. From failed inputs/outputs and your motor not running to over-current alarms and ground faults we have experience in repairing these problems. The products we service daily come from a wide range of applications: from Industrial CNC machines and hospital elevators to factory conveyor and industrial crane systems.

With that diversity in mind, Precision Zone has custom built simulators to fully test your AC or DC drive before the repair to identify the failures, and after repair to ensure the drive is ready for the actual production conditions.

What are AC Servo Drives?

Servo drives are electronic devices designed to control the operation of electric servomechanisms, most typically electric motors. Servo drives operate the motors by analyzing the signal from the motor feedback devices and continuously adjusting control signals to ensure desired motor performance within the closed loop system.

AC servo drives are paired with AC Servo motors. AC Servo Drives issue commands to the motor and receive feedback input to ensure the controlled motor performs a desired motion. AC Servo Drives continuously monitor the motor status by reading the feedback or sensor information. Feedback data signals the drive to perform continuous adjustments to achieve the needed velocity, torque, position, stiffness, damping, and feedback gain of the controlled AC servo motor.

What are DC Servo Drives?

Servo drives are electronic devices designed to control the operation of electric servomechanisms, most typically electric motors. Servo drives operate the motors by analyzing the signal from the motor feedback devices and continuously adjusting control signals to ensure desired motor performance within the closed loop system.

Unlike AC servo drives, DC servo drives convert Alternating Current (AC) into Direct Current (DC) to control the DC Servo motors they are paired to. Single-phase DC servo drives operate in half-bridge mode by generating a half cycle of DC output from a single phase of AC input. Three-phase DC servo drives are equipped with 6 SCR’s that allow them to operate in full-bridge mode to generate a DC output from a 3 phase AC input.

AC Spindle Motors: Elevating Machine Performance

AC Spindle Motors are a pivotal component in the machinery landscape, driving the performance and precision of numerous machining and manufacturing processes. These motors, known for their high-speed capabilities and exceptional reliability, play a crucial role in optimizing the efficiency of CNC machines, lathes, milling machines, and more.

Our collection of AC Spindle Motors is curated to meet the diverse needs of the modern industrial sector. By integrating these motors into your equipment, you can expect a significant enhancement in operation speed, accuracy, and overall productivity. Designed to deliver consistent power and performance, our AC Spindle Motors ensure your machinery operates at its peak, day in and day out.

Featuring advanced design and engineering, our AC Spindle Motors offer improved torque management, reduced heat generation, and increased energy efficiency. This translates into longer motor life, reduced operational costs, and minimized downtime for maintenance. Whether you're involved in high-precision tasks or high-volume production, our spindle motors provide the reliability and performance necessary to meet the demands of your specific applications.

Invest in our AC Spindle Motors to transform your machinery's capabilities and push the boundaries of what's possible in your manufacturing operations. Experience unparalleled performance and precision with our cutting-edge motor solutions.

DC Spindle Motors: Powering Precision in Advanced Applications

DC Spindle Motors represent a critical technology in the realm of advanced machining and manufacturing, offering tailored solutions for applications demanding precise control and smooth operation. Characterized by their direct current design, these motors provide the finesse and adaptability required for detailed work in CNC machining, engraving, and high-precision milling operations.

Our selection of DC Spindle Motors is specifically designed to cater to the nuanced needs of industries seeking meticulous control over their machining processes. These motors are engineered to deliver superior speed regulation, allowing for exacting control over the cutting and shaping of materials. The result is an unmatched level of accuracy and finish quality, essential for industries where precision is paramount.

Beyond precision, our DC Spindle Motors are built for durability and efficiency. They offer a compact design that integrates seamlessly into various machine architectures, optimizing space and enhancing machine aesthetics. With lower maintenance requirements and robust construction, these motors ensure long-term reliability and reduced operational costs.

What are Variable Frequency Drives or Inverters?

A variable frequency drive (VFD) controls a motor’s velocity of rotation by modulating the frequency of the incoming AC voltage between the US standard 60 Hz all the way down to 0 Hz.  Depending on the application, VFDs can perform a continuously variable speed change or by switching between the preset speeds.Within the VFDs, this modulation is occurring in three stages:


  1. The first stage rectifies the incoming Alternating Current;

  2. The second stage charges a DC capacitor bank called the “DC Bus”;

  3. The final third stage, driven by a microprocessor and commonly known as a “power inverter”, modulates the energy stored in the DC Bus in the form of a PRM output (typically a 4 KHz carrier) that allows you to control the motor speed and torque.


It is often due to this last stage that VFDs are referred to as “inverters” which confuses some to believe the VFDs and Inverters are different devices.

Great customer service and company. I had a Turret Drive go dead on my CNC. I sent it in for repair and was told it was not repairable. They worked on trying to source parts to get the drive back up and running. It is Dec 2023 and my Drive is from 1997. Well, they were able to find parts to fix the drive. I installed the drive and my machine is now back up and running. I will definitely use Precision Zone in the future.

My company has used Precision Zone in the past, with great results. We again turned to them for repair on one of our CNC components. They had the part we needed in stock, it shipped out the following day, and we were able to send in our damaged component for a core charge refund. They made the whole process quick and easy, for a fair price. Will definitely be using them again.

These guys are absolutely amazing!! They were able to do major repairs that I thought would seriously cost us a ton. Not only did they fix my Y Axis servo Module and tool changer encoder at a very affordable price but did it very fast. I pulled the parts I knew were faulty; mailed them out to Precision Zone and they were repaired quickly and returned to me so I could get back to business. Very impressed and will use them again in the future.

Had to share this. I call about an item, they check it out for me with a pronpt returned call(first good impression). I go to order the part online after the clarifications and realize i was asking for the wrong size to begin with, my fault entirely, so i order the correct item. I immediatly get a call from them wanting to make sure i got the right part, instead of the one i asked about. Wow, talk about buying with confidence. This group is on top of it no joke. That and im buying a hard to find well made german product so it makes sense the service is on par with the product. Very impressed.
