Counter Balance Drive Motor



The core advantage of this AC drive motor lies in its exceptional energy efficiency and silent operation technology. Within a low-voltage system ranging from 32V to 55V, the motor achieves a rated efficiency of up to 91%—a factor directly contributing to the vehicle's driving range per single charge. In terms of operational comfort, the motor strictly limits running noise to under 60 dBA; this is crucial for effective noise control in multi-vehicle operations within modern automated warehousing environments.
Regarding power control precision, the motor delivers a rated torque of up to 107 N·m, ensuring ample torque response when the vehicle initiates movement on inclines or performs heavy-load towing. To guarantee the absolute safety of the powertrain, the motor comes standard with a Thermal Protection feature that monitors winding temperature rise in real-time, thereby preventing electrical damage caused by prolonged high-load operation. With an insulation resistance of ≥50 MΩ and an IP54 protection rating, the motor remains fully operational even in dusty, humid environments such as cold storage facilities or logistics terminals; utilizing its sophisticated low-voltage AC variable frequency technology, it delivers smooth, linear speed control and efficient energy recovery.
