The TDH Model ac hub wheel drive is designed to provide higher efficiency and smaller size than traditional dc drives. It's suitable for the maneuvering of 24 and 80 V battery-powered devices such as automatic guided vehicles, lift trucks, pallet trucks, and other types of construction equipment. It uses synchronous ac motors, which are available in 400 and 600 W versions, and requires no maintenance. Its compact design combines a helical two-stage gearbox, ac motor, brake, and wheel with an integrated sensor bearing for speed feedback.
