ISO 9001:2008 certified with Total Quality Management policy. We continuously upgrade repair work standards, monitor through internal and external audits, and reduce non-conformances to at least 0.01% of monthly sales. All fully repaired machines carry a six-month guarantee with detailed test certificates.
Extensive testing including Surge, Hipot, Megger and Tan Delta using sophisticated winding analysers. Early warning detection prevents unexpected motor failure. Our services ensure electrical machines operate efficiently with minimal downtime across mining, manufacturing, agriculture and power generation sectors.
Over 55 years in Zimbabwe with branches in Bulawayo and Harare. Our team has decades of experience in electrical and mechanical engineering repairs, rewinds, dynamic balancing (up to 14 tonnes), TIG winding analysis, laser alignment, white metal bearing maintenance, and redesign for speed, voltage or output changes.
Coil manufacturing plant for up to 11kV coils (hairpin, diamond, DC pole & armature coils using VPI and resin-rich processes). Slip ring manufacture, machining of electric motor parts, TIG welding of commutators, white metal bearing maintenance, shaft pressing, and resin-glass banding.
Rewinding of electric motors from 1/4Hp up to 10,000Hp up to 11kV AC. Repairs and rewinding of DC motors, armatures, and plugger pumps using locally manufactured coils. Winding specs are verified using computer-aided programmes to ensure motors run at optimum performance. Rewound motors go through rigorous in-process testing including Surge, Hipot, Megger and Tan Delta where necessary using sophisticated insulation testers and winding analysers.
Learn MoreBAW has the capacity to rewind transformers up to 7.5MVA including online oil purification. Services include transformer repairs, pressure testing up to 160kV, no-load run testing, TIG winding analysis, surge comparison tests, Megger ohm, Hipot and Tan Delta testing. Comprehensive after-sales service and root cause analysis for transformer failures. Transformer oil filtration available in workshop and on site.
Learn MoreBAW's Vacuum Pressure Impregnation for rewinds provides complete sealing of the winding against moisture and vibration, providing greater mechanical strength and improved corona protection. This process improves performance and reliability of machines working in harsh working environments such as mining, agriculture and heavy manufacturing.
Learn MoreOur IRD 260 Dynamic Balancing machine can balance rotating elements of up to 14 tonnes. Correct balancing is essential for acceptable performance and is carried out on all machines before they leave our workshops. An on-site balancing machine, the IRD 246, is used by our field staff to check and balance machines on site. Condition Based Monitoring identifies rotor unbalance, misalignment, mechanical looseness, eccentric rotor, belt drive problems, gear problems, resonance, bent shaft, rotor rub, bearing problems and induction motor issues.
Learn MoreSurge testing is the only known method of determining the interturn insulation strength in a coil or winding. Weak or deteriorating insulation leads to interturn shorts. By means of periodic testing, the normal degradation process can be monitored. The early warning usually provides ample time to repair or replace before motor failure occurs.
Learn MoreMechanical repairs include housing repairs, shaft modifications, slip ring manufacturing and repairs, commutator rebuilds, metal spray/remetalling, TIG welding and machining. Our redesign capabilities include change of motor speed (number of poles), change in voltage and increase in motor output. We also offer laser alignment, commissioning of service motors inclusive of vibration analysis, and white metal bearing maintenance and air gap adjustments.
Learn MoreBAW offers 24hr backup service, free collection and delivery anywhere in the region, product follow-up, and condition-based monitoring. We will collect, repair and deliver motors anywhere in the region. All motors fully repaired carry a six-month guarantee. Strategic synergies with Original Equipment Manufacturers (OEMs) for after-sales service, customer support and outsourcing partner services.
