BIQU 42HDB4036Z-24B 1A Nema 17 Motor 1.8 degree Class F High Temp Motor

This is a great standard Nema 17 motor, insulation class F means it can be used safely in enclosed spaces. This is our standard spec for our Rook printer kits, but works great on most 3D printers. Comes with a 1m long motor harness. Specifications High:40mm Shaft length:22mm Color:Black Phase number:2 Rated voltage:DC 3.6 Vs Phase resistance:3.6*(1+10%) / phase Steering（shaft extension):A-AB-B-clockwise Maximum no-load operation frequency:＞1000 PPS Electrical strength:AC600V/1mA/1S Moment of inertia:73 g.cm ² Holding torque:≥450mN.m   Step angle:±1.8° Rated current:DC 1.0a/phase Phase inductance（1kHz）:8X（1+20%）MH/phase Positioning torque:25mV.m REF. Maximum no-load starting frequency:≥800 PPS Insulation resistance:≥100MΩ（DC 500V） Insulation class:Class F Quality:0.28Kg REF Please note: These are categorized as "high temperature" motors, they have a higher insulation class than standard motors and are intended to perform better at higher currents and higher ambient temperatures. However running at or near full amperage in environments higher than 40C will impact longevity. We generally recommend for higher temperature environments to lower your amperage to increase the life of the motor.
