EZ Motor Speed & Torque Chart
• Flat Torque Curve
• Higher Torque available
even with higher speeds
• Increase Torque by 35%
with Cooling Options
Z: Zhan = Teeth
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

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
Advantages
 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)
