The motor can be horizontally or vertically mounted. When it is mounted in direction
3:
● Note the permissible axial force of the motor (gravity of the drive unit) and the IP
rating requirement.
● If a oil seal is used, oil may enter the motor.
● Ensure that the direction is suitable for operation conditions.
Heat dissipation
The MS1 series motor is naturally cooled. The internal heat is consumed through heat
conduction, heat radiation and natural convection. A heatsink is used for heat
conduction. For details, see "

. To ensure adequate
heat dissipation, at least 100 mm spacing between adjacent parts is recommended
on three sides.
When the motor is used together with a reducer, the motor needs to be derated.
Installation cautions
The mechanical and electrical installation of the motor must be performed by trained
professionals:
● Obey the data on the nameplate and the warning labels attached to the motor.
● Ensure that the environmental conditions of the installation site (such as
temperature and installation height) meet the requirements. It is forbidden to use
the motor in explosive environment.
● Thoroughly remove the preservative from the shaft extension with a commonly
used solvent.
● To ensure heat dissipation, install a heat sink between the machine tool and the
motor. The larger the heat sink, the better the heat dissipation. The recommended
size and material of the heat sink are as follows:
● MS1H1/MS1H4: 250 × 250 × 6 (mm) (aluminum)
● MS1H2‑10C to 25C: 300 × 300 × 12 (mm) (steel)
● MS1H2‑30C to 50C: 400 × 400 × 20 (mm) (steel)
● MS1H3‑85B to 18C: 400 × 400 × 20 ((mm) (steel)
● MS1H3‑29C to 75C: 360 × 360 × 25 ((mm)
(aluminum)
Do not put an insulator, such as a pad, between the servo motor and heat sink,
otherwise motor temperature will rise and the motor may fail.
● For vertical mounting with the shaft extension upwards, ensure that no liquid
enters the upper bearing.
● When using a motor with an oil seal, you must lower the oil level to the lip of the
oil seal.
