  20. What are the challenges?

  21. Accuracy vs. Precision • Accuracy is not the same thing as precision. • "Accuracy" represents the ability to get closest to the true point you are expecting. • "Precision" measures the ability to repeat a move and get back to the same point (regardless of accuracy).

  22. Ideal

  23. Low Accuracy High Precision

  24. High Accuracy, Low Precision

  25. Mechanical Servo Motor STIFFNESS

  26. System Parts

  27. What is a Linear Shaft Motor? It is a direct drive linear brushless servomotor!

  28. What is a Linear Shaft Motor? • Design Concept • Simple • High precision • Non-contact

  29. What is a Linear Shaft Motor? • Design Concept: Simple • Only two parts

  30. What is a Linear Shaft Motor? • Design Concept: High Precision • Coreless design • No iron in forceror shaft • No cogging • Stiff design • The coils themselves are the core, thus the stiffness of an iron core design

  31. What is a Linear Shaft Motor? • Design Concept: Non-Contact • Large Air Gap0.5mm to 1.75mm nominal annular air gap • Non-criticalNo variation in force as gap varies over stroke of device

  32. Basic Specs

  33. Basic Specs

  34. Basic Advantages • No lubrication or adjustment necessary • Eco-Friendly - no noise, no dust • Extremely high precision[1], low speed uniformity, and high repeatability • Realizes high speed motions while retaining high precision [1] The precision of repetitive positioning is dependent on the resolution of the linear encoder. In addition, it is also necessary to have sufficient machine rigidity. In the same way, the absolute positioning precision is also fundamentally dependent on the linear encoder. It is practically not dependent on the expansion or declination caused by the heat of the Linear Shaft Motor.

  35. Used with 8.6nm resolution encoder Distance（mm) Time(s) Used with 8.6nm resolution encoder Distance（mm) Repetition Positioning Accuracy • Available within ±1.2 pulses of encoder resolution （3σ）（encoder resolution：less than １０ｎｍ） • No influence with Expansion and contraction of a shaft Time(s)

  36. Precise Positioning :Enlargement High Precise Positioning up to±0.1μm,without overshoot ModelS160T Condition 　Ｖmax≒１ｍ／sec αmax≒１Ｇ

  37. Basic Advantages • Good resistance against environmental changes such as temperature • Reduce number of BOM parts • Saves space • Lower power requirements • Simplifies QC

  38. Force Constant

  39. Velocity（V)Current（A) Current（A) Velocity（mm/s) Time Current in Movement • Only at the time of an acceleration and slowdown, current flows. • In case of a linear motor with a core, about 30% of rated current flows even at the time of constant speeding

  40. Temperature Increase on a Table Load：1kg, V max=1m/s, αmax=1 G Stroke：200mm( Round movement after 1sec stop at at the both ends) Temperature on the table Temperature in the room Temperature increase = Temperature on the table – Temperature in the room Process time Temperature（C)
