Should I Replace My Motor or Rewind It?

Is your motor showing signs of wear and tear? Have you been surprised by the cost of a new motor? Before you decide, consider this: rewinding your motor at Academy Pump and Motor could save you up to 60% compared to buying a brand new one. Plus, it's an environmentally friendly option with a much lower carbon footprint compared to manufacturing a new motor.

When to Rewind vs Replace:

Here are the signs that indicate you should consider rewinding your motor: visible wear like burns, broken parts, moisture, or rust; undamaged laminations; decreased winding resistance, which may indicate shorted coils in the motor; issues with insulation resistance; and if your motor is under 15 years old. These factors suggest that a motor rewind could be a cost-effective solution to restore its efficiency and performance.

Signs you should REPLACE:

Here are the signs indicating that you should consider replacing your motor: the magnetic core is in poor condition; your motor is over a decade old; the motor has been improperly rewound in the past; there is irreparable damage to the motor; and bearing failure has led to the armature grinding against the stator. These issues suggest that replacing the motor might be necessary to ensure reliable operation and avoid further damage.

When deciding whether to rewind or replace your motor, consider the potential savings from using a more energy-efficient motor. Compare the performance of your old motor to a potential new one to make an informed decision.

Our Shop’s Rewind Process

At Academy Pump and Motor, we prioritize ensuring that your motor rewind is completed with precision and efficiency. Here’s a detailed look at our process:

We begin by taking precise measurements of the incoming stator core and processing the data using our core-loss software to determine the weight of the core steel. Following this, we perform a core test to gather pre-burn data, and then proceed to cut opposite connection end turns in a random wound pattern. Prior to initiating the burn process, we insert a burn oven temperature RTD by drilling a hole in the copper, placing the stator in a temperature-controlled oven adjusted according to its size. Throughout this process, we closely monitor the temperature electronically and allow the stator to normalize to room temperature afterward to prevent any potential warping or cracking. Subsequently, we collect winding data from the unit and, if necessary, verify or redesign through our meticulous verification process. We take care during the wiring removal to prevent splaying of the iron teeth and utilize walnut shell blasting to prevent lamination roll-over and shorting. After the stator is cleaned, we conduct a post-core test to ensure any alterations are within acceptable limits, with a maximum efficiency rating of 4 watts per pound. Finally, we prepare the stator for insulation system installation following a thorough post-core test and hot spot check. At Academy Pump and Motor, each phase is conducted meticulously to deliver a restored motor that aligns with our stringent standards of excellence in quality and performance.
