• (1)When selecting products, use Table 1 to determine the service factor corresponding to the motor type and operating conditions.
• (2)Calculate the correction torque (T’) by multiplying the load torque (T) by the service factor (SF) in Table 1. Select a model having an allowable torque greater than or equal to the correction torque. (See Table below. )
• (3)Check that the required bore diameter is less than or equal to the maximum bore diameter of the selected model. If the required bore diameter is more than the selected model’s maximum bore diameter, select a different model satisfying the required bore diameter. (See Table below. )
• (4)When using direct motor coupling, refer to the selection tables, Table 2 and Table 3.

Torque calculation method

T = 9550 × P n   T = 974 × P n

• T = Load torque N・m {kgf・m}
• P = Power transmission kW
• n = Speed r/min
• T' = Correction torque N・m {kgf・m}
