then

The formula of cos phi in single phase motor
Cos phi = P / (V I)
or
Cos φ = P / (V I)

====================================

Cos phi = 200 / (220 * 1.24)
Cos phi = 0.733.

:2: In the paper bag factory has an electric motor that has specifications: voltage is 200 Volt single phase, frequency is 60 Hz, current of electricity is 9.5 Ampere and real power on the name plate is 1.5 kW. How many cos φ of electricity of the motor?

:catat: Answer:
V = 200 Volt
f = 60 Hz

Cos φ = P / (V I)
Cos φ = 1500 / (200 * 9.5)
Cos φ = 0.79.

:3: The electric motor has specifications: voltage is 400 Volt single phase, frequency is 70 Hz, current of electricity is 10.97 Ampere and real power on the name plate is 4 HP. How many cos φ of electricity of the motor?

:catat: Answer:
V = 400 Volt
f = 70 Hz

P = 4 HP → convert HP into W → 4 * 746 W = 2984 W
Cos φ = ...?

Cos φ = P / (V I)
Cos φ = 2984 / (400 * 10.97)
Cos φ = 0.68.

BSH 222 is a Type of Push Button Switch

Kasuga BSH 222 is a type of push button switch, which has an ON button and an OFF button in one switch. ON button BSH 222 marked with black color, position above OFF button. OFF button BSH 222 marked with red color, position below ON button.

BSH 222

PTM and PTB

ON button in a BSH 222 switch is type of PTM (push to make) non latching. OFF button in a BSH 222 switch is type of PTB (push to brake) non latching. Picture below is a symbol of BHS 222 switch.


Contact Capacity

Electric voltage and current capacity of the contact point BSH 222:
250 V max 5 A
500 V max 1 A.
