1 General information Product Description and Overview of Types. General information Power and torque The details on power and torque given in the catalog refer to mounting position M and similar mounting positions, where the input gear stage does not completely run under oil. In addition, the gearmotors are assumed to be standard versions with standard lubrication and under normal ambient conditions. Please note that the motor torques shown in the selection tables for gearmotors is subject to selection. However, the output torque for the desired output speed is essential for the application and needs to be checked. Noise levels The noise levels of all SEW servo gearmotors and servomotors are well within the maximum permitted noise levels laid down by the VDI guideline 59 for gear units and EN for motors. Coating The servo gear units, synchronous servomotors and servo gearmotors from SEW- EURODRIVE will be coated as follows: Type BSF../PSF.. servo gear units with adapter DS../CM.. synchronous servomotor BSF../PSF.. servo gearmotor Coating black RAL 9005 Special coatings are available on request. Weights Please note that all weights shown in the catalog exclude the oil fill for the gearmotors. The weight varies according to gear unit design and gear unit size. The lubricant fill is dependent on the mounting position, and consequently it is impossible to make any generally valid statements. Please refer to "Lubricants" in the "Design and Operating Notes" section for recommended lubricant fill quantities depending on the mounting position. The exact weight is given in the order confirmation. Heat dissipation and accessibility Servo gearmotors and the brake can reach high surface temperatures > 00 C during operation. Make sure to maintain adequate distance from heat-sensitive components when installing gearmotors/brake motors to the driven machine. Please also refer to the notes on the motor dimension sheets in this regard. NOCO fluid for protection against contact corrosion As standard, all shaft-mounted gearmotors are supplied with NOCO fluid, a paste that prevents contact corrosion. Use this paste in accordance with the information in the gear unit operating instructions. It simplifies service work and removal of the unit. NOCO fluid is food grade according to USDA-H. You can tell that NOCO fluid is a food grade oil by the USDA-H identification label on its packaging. 8 (BSF.., PSF..)

2 General information Brake motors International markets On request, motors and gearmotors can be supplied with an integrated mechanical brake. The SEW-EURODRIVE brake is an electromagnetic disk brake with a DC coil that releases electrically and brakes using spring force. The design principle means the brake is applied if the power fails. This means it complies with fundamental safety requirements. The brake is activated by a brake control system housed either in the wiring space of the motor or in the control cabinet. A significant feature of the brakes is their very short length. The brake bearing end shield is a part of both the motor and the brake. The integrated construction of the SEW- EURODRIVE brake motor permits particularly compact and sturdy solutions. SEW-EURODRIVE is a member of the AGMA (American Gear Manufacturer s Association), and as such, all its gear units and gearmotors conform to AGMA specifications. We supply motors for connection conditions according to CSA and NEMA standards on request (registered with UL). For the Japanese market, we offer motors conforming to JIS (Japan Industrial Standard). Contact your sales representative to assist you in such cases (BSF.., PSF..) 9

3 Description of servo gear units. Description of servo gear units General nformation BSF.. helical-bevel servo gear units are two-stage gear units for applications in servo technology. They consist of a helical gear stage at the input and an axially shifted helical-bevel gear stage at the output. The housings are made in one part and standard equipment includes B5 retaining flanges at the output. The BSF.. helical-bevel servo gear units can be mounted to the foot or face side in an optional design. The gear units are available with four different output shaft designs. The PSF.. planetary servo gear units are single and two-stage planetary gear units. They are used in servo technology applications as well. The housings come equipped with B5 retaining flanges at the output as standard. The gear units are available with two different output shaft designs. Direct motor mounting The new servo gearmotors from SEW-EURODRIVE make it possible to mount servo gear units directly to the synchronous servomotors from SEW-EURODRIVE without an adapter. These integrated servo gearmotors offer shaft-hub connections that are all positive and free from backlash. Motor mounting Use the modular motor adapters to connect all other commercial servomotors in a simple and time-efficient manner to the servo gear units from SEW-EURODRIVE. 0 (BSF.., PSF..)

4 Characteristics of the SEW-EURODRIVE servo gear units.3 Characteristics of the SEW-EURODRIVE servo gear units Low backlash and positioning accuracy Extensive ratio range with fine graduation Low noise Reliability, longevity and low maintenance High overload capacity Compact and lightweight structure Torsionally rigid The optimum gearing geometry paired with highest precision of the manufactured components and careful assembly make for low circumferential backlash. The BSF.. helical-bevel servo gear units and the PSF.. planetary servo gear units ensure a low circumferential backlash even in their standard designs. The circumferential backlash can be further reduced for all types and even minimized for PSF.. planetary servo gear units. Circumferential backlash will remain constantly low for the entire gear unit life due to the wear-free operating performance and high-endurance design of the running gears. All ratios from i=3 to i=00 are integers and finely graduated. This means the gear units are particularly suited to applications in controllers in which it is important to have divisible resolution values in terms of encoder increments. All external gearing components are ground, which ensures low noise development in all speed ranges. The high reliability of servo gear units from SEW-EURODRIVE in the system is ensured by the use of high-strength materials, high-quality anti-friction bearings, long-lived oil seals and synthetic lubricants. Exactly matched components as well as backlash-free and positively connected drive elements ensure that highest torques can be transferred and that large axial and radial forces can be absorbed. The high power density allows for integrating the gear stages in a compact, single-part and extremely solid cast housing of small dimensions. The special design of SEW-EURODRIVE servo gear units in conjunction with large shaft diameters ensures high torsional rigidity (BSF.., PSF..)
