PHK-EZ angle planetary servo geared motor

Features of the PHK-EZ angle planetary servo geared motor

• Compact and highly dynamic thanks to the direct mounting of the servo motor to the gearbox.
• Output shaft designed as a rotating flange shaft.
• Quiet operation – achieved through helical gearing.
• High precision – available with standard or reduced backlash.
• No positioning errors – fractional gear ratios available.
• Maintenance-free – no oil change required.
• Mounting position to be specified upon ordering.
• Ambient temperature: 0 °C to 40 °C (other ranges available upon request).
• Filled with synthetic grease CLP HC ISO VG 150.
• Maximum permissible gearbox temperature (on surface) ≤ 80 °C.
• Protection class: IP65.
• Standard output shaft seal made of NBR.
• For duty cycles > 60% and higher ambient temperatures, FKM radial shaft seals on the output are recommended.
• Cast iron housing.
• Painted black RAL 9005 (other colors available on request).

Optional Configurations of the PHK-EZ angle planetary servo geared motor

• Protection class IP66 – splash-proof and dust-tight.
• Reinforced output shaft bearing.
• VITON FKM shaft seal.
• With modular output gear on the gearbox output shaft.
• With Mobil CIBUS 150/220 oil for food industry applications (NSF H1 approved).
• Oil expansion tank for vertical mounting position.
• With ME/MEL adapter and coupling for market-available servo motors.
• Angular servo gearmotor PHK-MB-EZ with two ServoSTOP safety brakes.
• Planetary gearbox PHK-ME with adapter and coupling (without servo motor).
