Lifting electric motors
The lifting three-phase electric motors are designed for application in the main motion of the rope and chain hoists. The brake of the cylindrical motors is electromagnetic, DC, and non-adjustable. Lifting motors are produced in different joining dimensions based on their application. Forced ventilation is also available if needed.
