Pole-changing electric motors
In many cases, pole-changing motors are also required as customised products with customer-specific requirements. We are the ideal partner for you here, as we can cover a wide range thanks to our specialised staff in combination with an extensive motor warehouse and our own final assembly. We offer motors with 2 or 3 speeds. The pole-changing three-phase motors can also be easily combined with our gearboxes. dahlander motors with 6 connection terminals are predominantly used.
Operating modes of three-phase motors
JS-Technik drives are available in the following operating modes: Continuous duty S1, short-time duty S2, intermittent duty S3 (without starting, without braking), intermittent duty S4 (with starting, without braking), intermittent duty S5 (with starting, with braking), continuous duty S6 (with intermittent load), reversing duty S7, continuous duty (with variable speed).
Design and terminal boxes
The design of the JS motors is variable on request. The feet of the motor can also be converted for the AC motors in the light version, i.e. from 0.12 kW to 7.5 kW. This means that a foot motor B3 can also be converted into a flange motor B5 or a foot/flange/motor B3/B5. Another advantage is that the electric drive can be converted into a terminal box position in KK-upper, KK-left, KK-right, even KK-bottom.
Efficiency classes for asynchronous motors
You can also obtain energy-saving motors in IE3 from JS-Technik. The most important efficiency classes are IE1, IE2 and IE3. The legal requirements for minimum efficiency levels are as follows: Since 16 June 2011, motors (0.75kW - 375kW) must be at least IE2 efficiency. From 1 January 2015, motors (7.5kW - 375kW) must be at least IE3 or operated as IE2 with a frequency converter. From 1 January 2017, motors (0.75kW - 375kW) must comply with at least IE3 or be operated as IE2 with a frequency converter. Pole-changing motors are exempt from the efficiency requirement and can be operated in IE1.
