●Connection Information● Technical reference ➜ Page G-1 Safety standards ➜ Page H-2 In 2-Phase PK Series, in addition to a standard type with a resolution of 200 steps per revolution (1.8˚/step), a high-resolution type (Resolution: 400 steps per revolution) and a geared type (high torque, higher resolution) are also available. The dedicated driver is required separately to operate the motor. A high-resolution type, high-torque, high-efficiency type, hightorque type, standard type, standard type with terminal box and SH geared type are also available. The basic step angle is 0.9˚, which is half that of the standard type. 400 steps per rotation is possible. This motor achieves high resolution, improved stopping accuracy and low vibration. ◇ High-Torque, High-Efficiency Type ● Lower Heat Generation Utilizing the latest in motor technology, the high-torque, highefficiency type stepping motors are able to achieve a significant reduction in the amount of heat generated from the motor. (There is a 50% reduction in temperature rise compared with conventional models.) Motor Case Temperature under the Same Operating Conditions 120 100 Stator Rotor Standard Type (50 teeth) High-Resolution Type (100 teeth) The small basic step angle allows the torque to increase sharply while minimizing the negative effect of frictional load.

Stepping Motors ● No Motor/Driver Relay The high-torque type provides, on average, 1.5 times higher torque than a standard stepping motor. By utilizing a larger rotor diameter, larger magnets can be used to significantly increase the output torque. Since the motor cable can be connected directly to the driver terminals, there is no need for wire connection or soldering on a relay terminal block.
