Packaging and logistics

All drives are nicely packed before shipment, suit for air cargo, sea transportation, and express delivery. CZPT ers are capable to phone its very own nominated forwarder or check with GTAKE logistics division for CZPT shipment services.

*  Low-electricity inverters are packed in cardboard box, and other folks are in plywood cases.

*  Plenty of transportation procurable globally in accordance with CZPT er demand from customers or GTAKE knowledge.





AC motors and gear motors include one-period motors for one-stage AC electrical power and a few-section motors for a few-phase AC electrical power. A solitary-section motor simply needs to be linked to a solitary-stage energy supply by way of the incorporated capacitors to operate. 3-phase motors do not need capacitors. You simply connect the motor right to the 3-phase AC power offer. Dongfang Electric offers a wide variety of AC motors and gear motors Constant or variable speed AC motors are accessible with single or three-period equipment and electromagnetic braking possibilities
