■
Location and environment for installation of motor
✔
Use the motor indoors free from any dust and corrosive gas.
✔
Operate the motor in the environment at an ambient temperature of 0 to 40 [°C].
✔
The motor is not dust-proof and waterproof design (IP30 equivalent). Use the motor in the environment
free from any water or oil.
✔
If the mounting base is not rigid enough for installation of motor, mechanical resonance may occur.
Remember to install and fix the motor securely onto the mounting base having high stiffness.
✔
Make sure that the motor mounting surface has a flatness of 0.02 [mm] or less.
✔
The motor may be installed in either orientation horizontal or vertical.
✔
For tightening torque and penetration depth of screws, follow the table below.
Motor model Screw Tightening torque [N
•
m] Penetration depth [mm]
PB1006 M4 3.4 or less 4 to 5.5
PB3015
M6 13 or less 7 to 8.5 PB3030
PB3060
Since the installation condition shown below can cause mechanical resonant vibration or failure of
estimation of magnetic pole due to low rigidity of the mounting base and the load, installation of
motor to mounting base and load to motor have to be secure and rigid.
✔
Allow the load to be directly applied to the motor rotor.
✔
Install the motor directly onto the mounting base.
