Item # PK564AE-T30, Stepper Motor with Taper Hobbed Gear

60 mm frame size and 93.5 mm motor length indicate a comparatively compact geared stepper motor format, while 4 N·m holding torque and 1.4 A/phase set the electrical and mechanical selection points for the driver and load. Gear ratio 30 :1, output step angle 0.024 ° and single basic step angle 0.72º mean the reducer is intended for finer output positioning than the motor step alone; backlash 10 arc min (0.17º) must still be included in positioning error where direction reversals are frequent.

Taper Hobbed Gear with Low Backlash up to 45 arc min and Offset Shaft defines the output mechanics, so mounting and coupling should account for the offset shaft layout rather than assuming an inline shaft. Shaft runout 0.002 in. (0.05 mm), concentricity 0.003 in. (0.075 mm), perpendicularity 0.003 in. (0.075 mm), radial play 0.001 in. (0.025 mm) max. of 1.12 lb. (5 N), axial play 0.003 in. (0.075 mm) max. of 2.2 lb. (10 N), and axial load 9 lb 40 N give the practical limits for alignment-sensitive mechanisms: excessive side or axial loading will directly affect gear output accuracy and bearing life.

Connection Type New Pentagon (Bipolar) Lead Wires - 5 and Motor Connection Type Flying Leads Shaft should be matched with the chosen driver wiring scheme before installation. Insulation resistance is 100 MΩ minimum when measured by a 500 VDC megger, dielectric strength is 1.5 kV at 50 Hz or 60 Hz for 1 minute, temperature rise is limited to 144ºF (80ºC), insulation class is Class B [266ºF (130ºC)] with UL recognition as Class A 221ºF (105ºC), operating temperature is 14ºF ~ 122ºF (-10ºC ~ 50ºC), and ambient humidity is 85% or less; these values set the boundary conditions for cabinet ventilation, insulation checks, and use in noncondensing environments.
