2. ELECTRIC CHARACTERISTICS

2.1 Max Voltage 60V

High Volt test 580V less than 9.5mAINSULAT F

2.2 KV:50-60RPM/V

2.3 Maximum constant current 40A

2.3.1 Test at 25A with locked rotor until thermal euilibrium

2.4 Phase resistance : <0.185Ohm lesser the better

2.5 Class F 155 Degree C OR H 150 Degree C windings

2.6 N 40SH Magnets high magnetized and high temperature tollerance

2.7 minimize cogging Torque

2.7.1 8 magnets 12 stator teeth and has excellent fluidity

2.8 Minize torque resistant to open phase(to minize minimum current unload

probably the requirement coincides )

3. CHARACTERISTICS PULLEY COUPLING

3.1 notch SHAFT 12MM

 4. CONSTRUCTION FEATURES

4.1 Motor mounting Flange with M6threaded Holes with thread at least 5mmdepth

4.2 limit radial and axial play and uncontrolled rotations of rotor to stator

4.3 Take care of assembly avoiding scrateching of the windings insulation

4.4 Quality support bearings, for high temperatures and able to tolerate

radial force on 25KG shaft at a distance of 10mm from shaft.

4.5 preferring mechanical joining elements (keys thread grains) to gluing

4.6 If adhensives are present , guarantee resistance to temperatures> 100 C

4.7 Check and correct static ( and possibly dynamic) balance of the motor.

4.8 General constructive guarantee infinite life to mechanics at torque of 8NM

4.9 Minimize moment of inertia of the motor, lightening the rotor where possible

4.10 Mechanic dimension must conform to the 3D STEP 2022 OSET90
