Electromagnetic
Clutch and Brake Units
125 Models
These are anti-drip clutches and brakes that have split-shaft constructions of clutch and brake within a light alloy housing.Power is output from the input shaft continuously to the output shaft. The output shaft is braked when clutch current is shut off and the brake is energized in response. These models come with either steel plate or cast (E type) mounting bases. Mounting is simple, and service life is long.
121-__-20G Models
These are open-mounted clutches and brakes that have through-shaft constructions of clutch and brake outside a light alloy drum.Power is output from the input hub continuously to the output shaft. The output shaft is braked when clutch current is shut off and the brake is energized in response. The construction holds up well under radial loads due to a wide bearing span, so it can be used under high tension when mounted with V pulleys, spur gears or the like. Thanks to the through-shaft construction, output is available at both ends of the shaft, so many mechanism layouts are possible, including using both ends in split driving or mounting a detection disc or the like on one end.
126 Models
The input shaft of the 125 models of clutch/brake unit are connected directly to general-purpose three-phase motors. The output shaft can be repeatedly started and stopped without stopping the motor, enabling higher frequency intermittent operation compared to turning the motor on and off.Chose either the base type or flange type of machinery mounting. Flange mountings have the same shape mounting surface as general-purpose flange motors, so they can be unitized with speed reducers.
CBW Models
These models mount a clutch and brake on the input shaft of a worm reducer to provide output from the speed reducer.The input is transmitted from a V pulley by belt. The V pulley at the input is installed as standard, so simply connect it to a drive with a belt and install the speed reducer to complete the mounting. No troublesome centering or processing is needed. Self-inertia is kept low by integrating the unit, so the efficiency of starting and stopping is good. It can be combined with a speed changer for a wide range of speed changes, and excellent performance can be achieved in many applications, such as 360°rotation stop of the output shaft.
CMW Models
These are models that combine a clutch/brake, worm reducer and motor to drive the input of a CBW model that unitizes a clutch/brake and worm reducer by a motor via a coupling.Concentrating the functions of the drive unit means a smaller installation footprint and eliminates the task of processing the mount and the like. Since the output shaft is simply engaged to the load, handling is easy.
121-__-10G Models
These share the same basic structure as the 121-[ ]-20 type clutch/brake units. They are double-clutch units that have a through-shaft structure and place clutches (101-[ ]-15 types) at both ends of the drum.The hub may be used as the input for two-stage speed-change/forward-reverse operation, or the shaft may be used as the input for power distribution or the like. Select the input method that works best for you. Just as with the 121-[ ]-20, the construction holds up well under radial loads due to a wide bearing span, so it can be used under high tension when mounted with V pulleys, spur gears or the like.
122 Models
These are double-clutch/brake units unlike any other that combine two clutches (101-[ ]-15) with a brake (111-[ ]-12) in a compact form factor.They provide high-precision positioning and applied control of complex operations from a single unit. The hub is used as the input for two-stage speed-change/fixed position stopping/high-precision forward-reverse operation. The output shaft is braked when clutch current is shut off and the brake is energized in response.
