At GEF Technologies, our operational excellence is supported by a highly functional workshop equipped with advanced tools and technology to facilitate our motor rewinding and transformer repair services.
Our robust 30-ton overhead crane is able to manage an extensive variety of lifting operations with remarkable efficiency and ease. Thanks to its impressive weight capacity, this versatile crane is suited for handling heavy loads in a multitude of industrial applications.
This 5-ton overhead crane is able to handle lighter lifting tasks within the workshop environment. Its design makes it ideal for efficiently moving materials and equipment, ensuring smooth operations for various applications.
Our washing bay is the designated area where motors and components are cleaned before inspection, repair, or rewinding. Proper cleaning ensures that contaminants such as grease, oil, carbon deposits, and insulation residues are removed, allowing for accurate diagnostics and high-quality repairs.
Our temperature-controlled oven is used for varnish curing and drying, which is essential to ensure proper insulation performance and durability of the motor windings. This oven is used to cure insulating varnish after the rewinding process, enhancing the mechanical strength and electrical insulation of the windings. We have a small and large version of this oven to cater to various motor sizes and frames.

Our Hi-Pot (High Potential) insulation tester is critical for evaluating the insulation integrity of stator windings, cables, and other electrical components. Low-frequency Hi-Pot testing is typically performed at 50 Hz or 60 Hz (power frequency) or at 0.1 Hz Very Low Frequency (VLF) for larger motors.
Our surge voltage tester (up to 5kV) is used to detect insulation weaknesses, turn-to-turn shorts, and winding faults in stators, rotors, and coils. This test applies a high-voltage surge pulse to the winding and compares the waveform response.
Our laser alignment tester is a precision tool to ensure accurate shaft alignment between motors and driven equipment such as pumps, compressors, or gearboxes. Proper alignment reduces vibration, bearing wear, and energy losses, leading to increased motor lifespan and efficiency.
Our bearing induction heater is used for heating bearings, couplings, and gears before installation. This method ensures a proper interference fit without damaging components, reducing the risk of premature bearing failure.
Our lathe machine is used for correcting housing and shaft journals, ensuring proper fitment of bearings, couplings, and other rotating components. A lathe allows for precise machining, polishing, and resizing of worn-out or damaged motor shafts, preventing misalignment, vibration, and premature bearing failure
Metal spraying is a critical process in an electric motor repair workshop for restoring worn-out shaft journals, bearing seats, and other rotating components. It allows for precise material buildup without the need for excessive machining or part replacement.
Dry-ice blasting is an advanced cleaning method used for removing dirt, grease, varnish, carbon buildup, and contaminants without damaging components. It is a non-abrasive, chemical-free, and eco-friendly solution that extends the life of electric motors and components.
A Horizontal Belt Drive Dynamic Balancing Machine is an essential tool for ensuring that rotating components meet international balancing standards, as specified in ISO 21940-21:2022. This advanced machine uses a horizontal belt drive system to accurately analyze and correct any imbalances in rotating components, resulting in smoother and more efficient operation.
