The synchronous motor speed is calculated with the following equation: \(N_{s}=\displaystyle \frac{120 \cdot f }{p}\) Where, N s is the motor speed in RPM. 8 Pole = 750rpm. Three studs opposite shaft end are 8-32 on a standard 2. Transcribed Image Text: An 8 pole, 50 Hz single-phase induction motor is running at 690 rpm. View: Sort by: CG Alloy GD100L 0. 3 Nm - 846. The number of poles and the frequency of this motor are: 4 poles 50 Hz. High purity copper windings maximize efficiency. 99 – £ 608. Developed from the outset for maximum convenience and easy handling, ABB General performance motors can be used in a wide range of industrial applications. The rotor resistance is 0. Slip at No-load Rotor spins at nearly n s, so n r =1798 typical for unloaded 4 pole motor 0. Calculate the synchronous speed using the given frequency and number of poles. Number of poles (p): For example, 4. Check out the deal on T Series Three-Phase Motor - 8 Pole, 160 Frame, 4. 4.
