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
