DIMENSIONS

DESIGN• Fully designed by Dynatech

– Mechanical design– Electromagnetic design

• Mechanical design– High quality materials– Shields are same for all models– Shaft and main body are tailored for

each model

• Shaft designed to hold more than 5000 kg of suspended load on sheave. Diameter: 75 mm

• Special steel, high elastic limit• Shaft without notch to prevent fatigue

cracks forming• Integrated encoder hole and braking

disc coupling.

SHAFT

• Finite Elements Method calculations• More than 5000 kg of suspended load

SHIELDS

• Optimized for low speed: from 37 rpm to 320 rpm

• Cogging reduction using skewed stator• Stator diameter optimized for maximum

torque• Specific winding for each model • Use of finite elements method

ELECTROMAGNETIC DESIGN STATOR

ELECTROMAGNETIC DESIGN COGGING ANALYSIS
