Asynchronous motor SMK series

AC110 V115 V

Low-speed synchronous motors provide highly precise speed regulation, low-speed rotation and quick bi-directional rotation. The basic construction of low-speed synchronous motors is the same as that of stepper motors. Since they can be driven by an AC power supply, they are sometimes called AC stepper motors. • Parallel Shaft Gear or Round Shaft (no Gear) • Single-Phase 115 VAC Low-Speed Synchronous Rotation The motor rotates at a speed proportional to and accurately synchronized with the frequency of the power supply. A fluctuation in load does not affect the rotation speed. • At 50 Hz 60 r/min (30 r/min for SMK014MA-*) • At 60 Hz 72 r/min (36 r/min for SMK014MA-*) Precise Positioning The motor can be stopped instantly by turning off the power supply. The stopping accuracy within the motor's permissible load inertia is ±10°. Continuous Rated Capacitor-Run Motor This is a capacitor-run motor that can be driven by a capacitor only. (An external resistance is needed for SMK5 type). This can be driven at a continuous rating even when bi-directional operation is required. Superb Starting, Stopping, and Reversing Characteristics If operated within the permissible load inertia, the motor can start, stop and reverse with 1.5 cycles (0.03 sec at 50 HZ, 0.025 sec at 60 Hz) of the power supply frequency. Vertical Applications Constant speed can be maintained even during lowering operations. Low-speed synchronous motors are suitable for applications where vertical operation at a constant speed is required.
