ZDSI series motors have two speeds: fast and slow. Besides matching with electric hoist, they are also suitable for machines requiring two speeds, such as lifting and transportation.

This series of dual motors is a composite motor with two conical rotor brake motors, ZDMI and ZDI, connected by a middle slow-speed drive device to achieve two speeds. Power: 0.5T ~ 16T, protection level IP44, IP54.
