VFD Compatibility with KII Series, Single-Phase, 220 /23 V AC Geared Motors

Postby essenceindia » Thu Dec 14, 2017 4:29 am

Hi !!
Good Day !!

You are requested to please let us know the VFD (Siemens V20) Compatibility with KII Series, Single-Phase, 220 /23 V AC Geared Motors (5IK90KG-5H10B), as our customer want to use this combination with variable speed controlling operation, please let us know whether this combination is suggestible ??

The customer is using Siemens V20 VFD drive input: 1-Phase, 220 / 230V, and Driver output: 3-phase, 220 /230v AC.

If it is suitable, whether it should be connect with capacitor (or) without capacitor ??

You are requested to please suggest / clarify all the options to proceed further in this matter.

Hi essenceindia,

In regards to your post, the 5IK90KG-5H10B is not a valid USA part number. From researching this model, it looks to be a version available on the Oriental Motor Singapore website. Although they would be able to assist you better with information on that product as well as any recommendations, here is what we were able to gather:

1.) The 5IK90KG-5H10B is a single-phase 220/230 VAC input motor. In order for the motor to be connected to a VFD (inverter) and have the speed controlled, then the motor would need to be a three-phase VAC input. With the three-phase induction motor, there would be no capacitor.

2.) The V20 VFD input is single-phase 220/230 and the output is three-phase 220/230, therefore the input of the motor would also need to be three-phase 220/230 VAC. Furthermore, the lowest VFD that I saw from the V20 was for a 0.12 kW (120 Watt) motor, however the 5IK90KG-5H10B is a 90 Watt motor which is below the VFD specification. Some VFDs allow you to run a smaller motor from the larger VFD and you need to adjust the current appropriately, however this is something that would need to be discussed with the VFD manufacturer as we have not tested these two part numbers together.

AC Motors for Stop + Start + Standby Application

Postby essenceindia » Fri Dec 22, 2017 8:29 am

Hi !!
Please let us know whether Cycle Time for Stop and start application (Stop max 0.5 sec + start max 0.5 sec + standby 3 to 4 sec), our AC Induction Motor / Reversible Motor / Brake Motor is suggestible ??

The direction of operation is only one direction, and operation to be required continuous by 24 hrs. in a day.
This is for Belt cutting operation, But positioning is not required for this application,

Please suggest us whether our AC motors can do for above start & start operation ??

Thanking you & Best REgards,

Hi essenceindia,

In regards to your post, a typical reference for the maximum cycling time of motors is 2 seconds (1 second on and 1 second off) for 6 ~ 40 Watt motors and 4 seconds (2 seconds on and 2 seconds off) for 60 ~ 90 Watt motors. Please note that this is a reference value for unloaded motors. When the motor is loaded, that will affect the cycling time. When cycling, the main concern is heat generation. Therefore, it is recommended to monitor the case temperature of the motor and ensure that the motor does not exceed 90 degrees C (194 degrees F). For a more detailed background on the cycling time, please reference the below link:

Based on the above information, you would need to test and make sure that the motor does not exceed 90 degrees C. Having the longer 4 second standby could help in keeping the motor temperature down, so the longer time you can allow the motor to cool, the better. Another option would be to consider a clutch brake motor. Clutch brake motors have a maximum duty cycle of 100 cycles/minute which make them ideal for applications involving frequent START/STOP operations. A link to the clutch brake motors is below:
