• 1 × NEMA 23 Stepper motor with pre-installed brake, MPN PHB57S112-404-ADB
Item Description
This stepper motor with pre-installed spring-applied brake (MPN PHB57S112-404-ADB) is supplied by one of the China's top stepper motor suppliers (PrimoPal Motor). It's a bipolar NEMA 23 hybrid stepper motor with 1.8° step angle (200 steps/revolution), made of high-quality cold rolled steel sheet and anti-high temperature permanent magnet. The rated current is 4.2A per phase, allowing for the holding torque of 280Ncm (368oz-in). This high-performance and high-reliability motor is terminated with 4 flying ended lead wires, and easily connected to the constant current or chopper drive controller. The pre-installed brake could help the user to prevent damage of the applications from the sudden interruption of power supply.
