General Specifications

Specifications		Motor
Thermal Class		130 (B) [Standard Type With Terminal Box: UL/CSA Standards is approved at 105(A).]
Insulation Resistance		The measured value is 100 MΩ min. when a 500 VDC megger is applied between the windings and the case under normal ambient temperature and humidity.
Dielectric Strength		Under normal ambient temperature and humidity, no abnormalities were observed even if 1.0 kV at 50 Hz or 60 Hz is applied between the windings and the case of the motor for 1 minute. (0.5 kV for frame sizes of 42 mm max., and 1.5 kV for standard type with terminal box PK29□D)
Operating Environment (In operation)	Ambient Temperature	-10~+50 °C (non-freezing)
	Ambient Humidity	85 % max. (Non-Condensing)
	Atmosphere	No corrosive gases or dust Should not be exposed to water or oil. (Standard Type with Terminal Box: No corrosive gases. Should not be exposed to oil.)
Temperature Rise		Unipolar: 2-Phase excitation at rated voltage, winding temperature rise 80 °C max. at standstill state (Resistance change method) Bipolar: 2-Phase excitation at rated current, winding temperature rise 80 °C max. at standstill state (Resistance change method) Aluminum heat radiation plates are attached to the following motors. PK24□D:115 × 115 × 5 mm PK26□D:250 × 250 × 10 mm *PKE24□D and PK26□JD are the same specification as unipolar.
Stop Position Accuracy^*1		±3 arcmin (±0.05˚), PK26□J, PK26□JD: ±2 arcmin (±0.034˚)
Shaft Runout		0.05 T.I.R. (mm)^*4
Radial Play^*2		0.025 mm Max. (Load 5 N)
Axial Play^*3		0.075 mm max. (Load 10 N) [Load 1 N for PK21□, Load 2.5 N for PK22□]
Concentricity of Installation Pilot to the Shaft		0.075 T.I.R. (mm)^*4
Perpendicularity of Mounting Surface to the Shaft		0.075 T.I.R. (mm)^*4

*1: This value is for full step under no load. (The value changes with the size of the load.)
*2: Radial Play: Displacement in shaft position in the vertical direction when a 5 N load is applied perpendicular to the tip of the motor shaft.
*3: Axial Play: Displacement in shaft position in the axial direction when a 10 N (1 N for PK21□, 2.5 N for PK22□) load is applied to the motor shaft in the axial direction.
*4: T.I.R. (Total Indicator Reading): The total dial gauge reading when the measurement section is rotated 1 revolution centered on the reference axis center.

Note

Disconnect the motor and driver when measuring insulation resistance, or conducting a dielectric strength test.
