1-1 Outline
The HC Series has been newly added to the Mitsubishi NC servomotor lineup. The HC Series
servomotor has the following features.
••••
Compact
By incorporating a new neodymium magnet, the L dimensions have been shortened by approx.
40%, by that contributing to downsizing of the machine. The shaft shape and flange size are the
same as the conventional HA Series servomotor, so replacement from the HA Series is possible.
••••
IP65
With the canon plug type and sealed structure, the machine is drip-proof against the entry of cutting
oil. In addition, the environment performance clears IP65 as a standard.
••••
Compatible with high-resolution detector
As with the HA Series, the HC Series has a max. 1,000,000 pulse/rev absolute position detector,
allowing high-accuracy control to be realized. 100,000 and 25,000 pulse/rev detectors are also
available. (The 1,000,000 pulse/rev detector is compatible only for the MDS-B-V1/V2/V14/V24
Series, and the 25,000 pulse/rev is compatible only with the MDS-B-SVJ2 Series.)
••••
Powerful motor brakes
All capacities of the HC Series servomotor are provided with magnetic release type motor brake
specifications. The holding torque has been increased by approx. 45% compared to the
conventional HA Series.
••••
Low-inertia series
The low-inertia specification HC
R Series has been prepared as a servomotor for use in NC
machine tool peripheral axes. This is compact and has a high power rate, so it is suitable for high-
speed positioning of peripheral axes. This also contributes to shortening the cycle time.
