  1. A Heritage of Innovation… STOBER Drives, Inc. – Maysville, KY • 1991: SDI opens with the ComTrac product line • 1993: MGS series introduced to US market • 1998: SPG planetary gearheads arrive • 2001: SMS product developed for US market • 2005: P/PH 2nd Generation • 2007: Integral Servo Gearing • 2008: MT50 & P9 • 2008: KS • 2009: MB & more Integral Servo Sizes • 2010: EZ Motors • 2011: EZF / PY Hollow Bore Motors • 1781 Downing Drive • 1780 Downing Drive

  2. STOBER Servo History • ES : (Electronic Servo) – Released in 1998 1stGeneration, Discontinued. Limited Spares, last production order placed in 2011 • ED: (Electronic Dynamic) – Released in 2005 2ndGeneration, still actively selling EZ will most likely replace by 2015 • EK: (Electronic Kompact) – Released in 2005 2ndGeneration, still actively selling EZ will most likely replace by 2015 • EZ: (Electronic Zahn (tooth) Wound) – Released in 2010 3rd Generation EZ: Stand alone motor and with Gearing EZF: Hollow bore Version PY_EZH: Hollow Bore Geared Motor EZS: Ball Screw driving version (2011) EZM: Ball Screw nut driving version (2011)

  3. EZ Motor Series • Patented technology • Tooth Winding • Short Length • High Torque

  4. EZ Servomotors – Even Shorter • Comparison: • EK501 to EZ501 • Example: • P5 Integral • Even Shorter than EK Series Compact Motors

  5. EZ Motor Data Without ventilation(Ventilation = +35%)

  6. EZ Motor Speed & Torque Chart • Flat Torque Curve • Higher Torque available • even with higher speeds • Increase Torque by 35% • with Cooling Options

  7. Z: Zhan = Teeth

  8. EZ / EZF Motors • Higher efficiency • Optimized electrical steel sheet - lowest lamination losses • Energy-saving – better than IE4 • Precise smooth running behavior • Punched and directly bonded laminated cores – low detent torques • High stability, low-vibration, low-noise Enlarged image of an orthocyclically linear-wound motor coil

  9. EZMotor with Tooth Winding Motor series EZ4, EZ5, and EZ7 with tooth winding – each with 12 teeth and 14 pole Example: EZ7 – motor with 4 magnets per pole

  10. EZMotor with Tooth Winding Optional Water Cooling

  11. EZMotor with Tooth Winding Hiperface encoder (Sick-Stegmann) With inductive absolute multi-turn encoder (Heidenhain EnDat)

  12. EZMotor with Tooth Winding EZ 503 High Dynamic (with low mass of inertia) Rotor Sheet Hollow

  13. EZ Motor with Tooth Winding EZ 503 Low Dynamic (with high mass of inertia) Rotor Sheet Filled with Material

  14. EZ Motor with Tooth Winding Optional Permanent Magnet Brake

  15. Forced Ventilation Option • Increases Torques up to35% • Suitable Voltages For Drive Mains • Single Phase • 230V AC +6%-10% • 50/60 Hz • Fan can be added in the field

  16. Forced Ventilation Option Compete Servo Fan Fan Housing Mounting Bracket Keeper Plate Power Connector

  17. EZ Available Motor Feedbacks • Tamagawa Resolver • Heidenhain EnDat Optical Single and Multi-turn Encoder - ECN 1113 & EQN 1125 • Sick-Stegmann Hiperface-Encoder Single and Multi-turn – SKS 36 and SKM 36 • Sick-Stegmann Programmable Incremental Encoder – CKS 36

  18. Feedback Codes

  19. Commissioning Instructions

  20. Feedback and Power Cables Pin-out to Match your Drive • Certified noise resistance • Torsionally resistant – (fit for cable carriers) • Flame retardant • Double shielding • Colors conform with DESINA • InterContec Connectors

  21. EZF Hollow Bore Motors

  22. EZF Hollow Bore Motors With absolute single-turn encoder Heidenhain ECI 119

  23. PY Hollow with Planetary Gearing

  24. PY Hollow with Planetary Gearing PY5 1-stage PY5 3-stage Water Cooling Option

  25. PY Hollow with Planetary Gearing • New design – Lubrication with grease Ratio: 1-stage=3 2-stage=9 3-stage=27 Option: Shrink ring Bearing Radial sealing replaced by labyrinth seal

  26. EZF / PY Absolute Encoder Heidenhain Absolute Encoder - ECI 119

  27. EZ / PY Water Cooling Option • Water Cooling Jackets available as an option • Increases torque by approximately 35% • Water jackets can be used for forced air. • To prevent condensation the water temperature must be limited to a delta of 10° Kelvin under ambient

  29. Catalogs and Brochures • On Web Site

  30. Ball Screw Drives

  31. EZS and EZM • EZS – driven ballscrew • EZM – driven ball nut

  32. EZS – Driven Ballscrew • Nominal torque 3.85 Nm to 23.7 Nm • Blind hole shaft • Axial double angular ball bearing • Grease lubricated • Ballscrew shaft extension must match shrink ring bore size (pilot hole diameter) of 20h6 / 25h6

  33. EZS – Options • Cooling • Forced Air • Water • Optional Permanent Magnet holding brake • Optional with additional inertia(not EZS 501 and EZS 701) • Encoder • EnDat 2.2, single and multiturn • EnDat 2.1, single and multiturn, optional with Sin-Cos signals • Resolver • Hiperface (in preparation)

  34. EZS – Water Cooling Optional water cooling in ‟A” side flange

  35. EZM – Driven Ball Nut • Nominal torque 3.6 Nm to 22.0 Nm • Continous hollow shaft • Axial double angular ball bearing • Grease lubricated • Ball nut mounting dimensions per DIN 69015-5, Type 0

  36. EZM – Options • Cooling • Convection cooled • Water cooling • Option with permanent magnet holding brake • Hollow shaft encoder • EnDat 2.1 • Single-turn resolution 19 Bit • Inductive absolute position encoder • 32 sine-cosine cycles/revolution • Power supply: 5V (+/- 5%)

  43. Support • Catalog provided per application • 30 piece minimum yearly potential • Brochure on Web Site

  44. 3rd Party Drives

  45. Examples of Modification • Water Cooling • Tolerance Bore • 42mm Shrink Ring • Roll Drive

  46. Selling Brief – EZ Motor • Optimized for Gearmotors – P, PH, KS, K, KL, F, C – Bearings, RPM • Ortho-cyclic Machine Tooth Wound – Wound by STOBER in Europe – 20 years experience • 14 poles provides high density • For use with 3rd party drives: – Many feedback options • Water / Forced Air cooling option • Video and Catalog on Web Site • Static and Running Sales Demos

  47. Highest Torque Density • 14 poles provide power and RPM for gearing • Shorter – eliminates right angle • Lower Inertia, more dynamic • Water Cooling • System Sell – harder to break into components • Lower Price (many times) Advantages
