Changduo Machinery Equipment is a specialist service company covering general motor repair, DC motor repair and high-voltage motor repair, taking on repairs of AC synchronous generators, synchronous motors, asynchronous (induction) motors and DC motors. Beyond motor repair, Changduo also offers transformer repair, technical upgrades and on-site inspection and maintenance. Its main clients are in the cement, mining, chemical and power generation industries, where it provides overhauls, on-site repairs and routine maintenance for all kinds of motors in production equipment. Years of work in these sectors have given the company a practical understanding of how their equipment operates. Changduo's repair work falls into three areas. DC Motor Repair covers repair, overhaul and on-site servicing of all types of DC motors, dealing with faults in commutators, brushes and windings, and suits DC-driven equipment in cement, mining, chemical and power plants. AC Motor Repair covers AC synchronous generators, synchronous motors, induction motors and high-voltage motors, from fault repair to complete overhaul, and suits production line motors that run continuously and where downtime is costly. Pump Motor Repair serves the motors that drive industrial pumps and plant equipment, offering repair as well as on-site inspection and maintenance to shorten downtime. In addition to motor work, the company repairs transformers and can carry out technical upgrades of motors based on actual operating conditions. Work is directed and managed by experienced electrical and mechanical engineers, and the company is well equipped with mature repair techniques. Each job follows five steps: the motor model and fault are discussed, an engineer inspects and diagnoses the unit, a repair or upgrade plan is agreed, the work is carried out as a workshop overhaul or on site, and the motor is test-run before being returned to service. When requesting a repair, clients can provide the motor type and model, power and voltage rating, fault symptoms and equipment location, so that the company can choose the repair mode and plan the return date around the downtime window.
