Motor
E design
The motor is a brushed DC motor, 12, 24 or 48 V DC. The
motor’s shaft is connected to a helical gear. The linear speed
depends on the load. The motor unit is surrounded by metal
housing and equipped by a EMC filter. The metal housing
cannot be opened.
S design
The motor is a brushed DC motor, 12, or 24 V DC. The mo-
tor’s shaft is connected to a helical gear. The line-ar speed is
controlled by smart PCBA but the max. speed depends on
the load. The motor unit is sur-rounded by metal housing
and equipped by a EMC filter. The metal housing cannot be
opened.
Gear unit
E design
The helical gear is directly powered by the motor shaft. Gear
unit is connected to the over load clutch that moves the drive
screw system.
S design
The helical gear is directly powered by the motor shaft. Gear
unit is connected to the drive screw system.
Integrated control unit (S design only)
The control unit consists of PCB with H-bridge to control the
motor, gears with nonius principle and hall sensor which ac-
quires the absolute position of actua-tor, temperature sensor
and micro controller that con-trol and monitor the function
including I/O and CAN bus communication and diagnostic.
Linear unit
The linear unit is surrounded and protected by the guiding
tube. The linear unit of the CAHB-21E or CAHB-22E is
equipped by brake. The push tube of the actuator is con-
nected to the nut of the drive screw unit and aligned by the
guiding tube.
