PHQK-MB-EZ Right-Angle Servo Drives with 2 Brakes

Combination of a PHQK Quattro planetary gearbox with a right-angle bevel gearbox, MB adapter, EZ servo motor, and two STOBER ServoSTOP safety brakes. Servogearmotors with a power range of 1.5 – 31.0 kW. Gear ratios from 22:1 to 583:1. Static brake torque: 8 – 100 Nm. Maximum output torque: 328 – 43,000 Nm. Rotational backlash: 1.5 – 4.0 arcmin. Efficiency: 92 – 93%. Optional features include a cooling fan, single-cable servo motor with EnDat 3.0 encoder, manual brake release, and reduced backlash. Available as a complete servo drive system with SB6, SD6, SC6, or SI6 motion controller.

 PHQK Right-Angle Planetary Gearboxes

• • Precision gearboxes with a choice of standard or reduced backlash.
  • Fractional gear ratios eliminate positioning errors.
  • Quiet operation thanks to helical gear teeth.
  • Maintenance-free, with no oil changes required.
  • Lubricated for the entire service life.
  • Mounting position to be specified when ordering.
  • Output shaft design: rotating flange shaft.
  • Ambient temperature range: 0°C to 40°C (other temperature ranges available on request).
  • Filled with synthetic grease CLP HC ISO VG 150.
  • Mineral oil for use in the food, beverage, and pharmaceutical industries available on request.
  • Maximum permissible gearbox temperature (measured on the gearbox surface): ≤ 80°C.
  • Protection class IP65, optionally IP66.
  • Standard gearbox output seal made of NBR, optionally FKM.
  • For duty cycles > 60% and higher ambient temperatures, FKM radial shaft seals on the output are recommended.
  • Optional reinforced output shaft bearings.
  • Cast iron gearbox housing.
  • Direct mounting of STOBER EZ/LM series servo motors without an adapter, coupling, or dual brake is possible.
  • Standard finish: black RAL 9005 paint (other colors available on request).

• The spring-applied brake is integrated into the motor adapter.
• Functions as a holding brake.
• Provides braking from full speed, for example in the event of a power failure or emergency stop in hazardous situations.
• Can operate as a single brake or in combination with the motor brake as a redundant braking system.
• Electrically actuated for dry operation.
• Equipped with a backlash-free plug-in coupling (jaw coupling), allowing easy motor removal while the axis remains braked in any position.
• Electrical release monitoring in the terminal box via a contactless, wear-free proximity switch.
• Manual wear monitoring by checking the air gap with a feeler gauge.
• FKM radial shaft seals with dual sealing lips.
• Four oil drain holes protect the brakes against oil contamination in the event of leakage.
• Differential-redundant system compliant with EN ISO 13849-1.
• Electrical connection as standard via a terminal box; optionally available with a plug connector (not possible in combination with release monitoring).
• In the de-energized state, braking is achieved by spring force.
• Released by a DC electromagnetic coil before motor start-up.
• Motor connectors or the motor adapter terminal box/plug connector are mounted in the 270° position.
• Combined with the motor brake, it provides a dual-brake solution with exceptionally compact dimensions.

EZ Servo Motors

• Permanent magnet synchronous electric motors.
• Rotatable plug connectors with quick-lock mechanism.
