Coal Mining Industry
PUTAI supplies industrial motors for coal mining and coal handling equipment, including conveyor systems, mine ventilation fans, pumps, winches, and other material-handling machinery. Our product range includes YBX3 and YBX4 series low-voltage motors for general industrial equipment, YBK3 series motors for underground mining applications, YBF3 series motors for mine ventilation fans, and YB2/YBX2 series motors for high-voltage applications.
Coal mining environments place specific demands on motor protection, insulation, cooling, and operating reliability. For underground applications, motor selection must also meet the applicable explosion-protection requirements and safety standards. The selection of YBK3, YBF3, and other motor series should be based on the equipment requirements, installation conditions, and applicable product approvals.
With over 25 years of experience in motor manufacturing, PUTAI supports OEM supply and replacement projects for mining equipment manufacturers and industrial users. Our manufacturing processes cover silicon-steel preparation, copper winding, insulation treatment, rotor manufacturing, VPI and drying for applicable windings, motor assembly, and finished-product testing. For new equipment and replacement projects, we review rated power, voltage, speed, mounting dimensions, cooling method, and protection rating to support motor specification matching and project requirements.
