PE Series: INLINE — Shaft Output PE Series Motor Mounting Plate Option (Motor information required with Motor Adapter option) STOBER ServoFit Gearheads fit the motor of your choice with the appropriate motor mounting plate assembled between the motor and the gearhead. NOTE: When ordering a gearhead: • Specify the motor manufacturer and part number • Provide the motor drawing with dimensions, or specify the motor mounting dimensions (per the list shown at right) For a precise dimension on a specific motor, or for general assistance, we recommend you contact STOBER Technical Support.

Overview Permissible Motor Tilting Torque I s F The permissible tilting torque of the motor attached to the gear unit is a result of the static and dynamic load “F” from the motor weight, mass acceleration, and vibration multiplied by the distance from the center of gravity “Is” of the motor. M 1k = F × I s < M 1K M 1K PE211 PE212 PE311 PE312 PE411 PE412 PE511 PE512 Nm 10 20 40 80 PE Permissible Output Shaft Load and Tilting Moments* Z 2 F 2A F 2R M 2K Unit mm N N Nm PE Series Load/Life/Speed Calculations All formulas shown are based on METRIC values Upper case letters are permissible values. Lower case letters are for existing values. The permissible load and tilting moment values are based on an output speed of 100 RPM. For higher speeds the following applies, where n 2 is the desired speed: F2AX = PE211, PE212 8 400 800 13 PE311, PE312 11 800 1600 40 PE411, PE412 13 1900 2400 73 PE511, PE512 16 4000 4600 206 * Refer to illustration and definitions below. During EMERGENCY OFF operation (maximum stops per gearhead = 1000) the permissible values in the table for F 2A , F 2R , and M 2K can be multiplied by a factor of 2. Rating based on output speed (n 2 ) of 100 RPM. For values at other speeds see below. F 2A 3 n 2 100 F 2RX = F 2R 3 n 2 100 M 2KX = The application output tilting moment should be determined by the following formula: M 2A = 2 • F 2a • y 2 + F 2rb • (x 2 + z 2 ) 1000 < M 2KB Where: F 2a Axial Load at Output Shaft F 2RB Acceleration Permissible Radial Load F 2A Permissible Axial Load M 2K Rated Tilting Torque F 2r Radial Load at Output Shaft M 2k Equivalent Tilting Load F 2R Permissible Radial Load z 2 Distance Factor M 2K 3 n 2 100 y 2 –F 2a +F 2r –F 2r x 2 +F 2a z 2 The hours of life (L h ) of the unit can be determined by the following formula: bearing life for duty cycle < 40% L h > 10,000 hours if M 2K /M 2A < 1.25 and > 1 L h > 20,000 hours if M 2K /M 2A > 1.25 and > 1.5 bearing life for duty cycle > 40% L hA = L h ( ) 40% Duty Cycle PE Series: INLINE — Shaft Output 800.711.3588 • www.stober.com ServoFit ® Precision Gearheads V.28 95
