Electric motors from a specialist contractor
JS-Technik GmbH is one of the leading suppliers on the electric motors online market in Germany. Our focus is on three-phase motors, frequency inverters and geared motors. You can also visit us via our subdomains elektromotor.co.
Size, power, speed and voltage of AC motors
On these pages, you will find a selection of electric motors of the size 63 - 355 with a power of 0.12 kW, 0.25 kW, 0.37 kW, 0.55 kW, 0.75 kW, 1.1 kW, 1.5 kW, 2.2 kW, 3,0 kW, 4 kW, 5.5 kW, 7.5 kW, 11 kW, 15 kW, 22 kW, 30 kW, 45 kW, 55 kW, 75 kW, 90 kW, 110 kW, 132 kW, 160 kW, 200 kW, 250 kW, 315 kW, 355 kW, 400 kW, 450 kW, 500 kW. A side from these sizes, medium-voltage motors are also available. JS motors are supplied in various speeds, i.e. motors with pole numbers of 2, 4, 6, 8 or 10, and international line voltages and frequencies, i.e. 230V/400V 50Hz or 265V/460V 60Hz and 400V/690V 50Hz or 460V/795V 60Hz.
Repair of electric motors
If an electric motor is defective and needs repairing, please do not hesitate to contact us. We have the required equipment and professionals having the expertise and long-year experience to do the job. But in many cases, a replacement with a new motor is more cost-effective than renewing the winding. We therefore recommend you to purchase a replacement motor from our large stock of motors and gearboxes. For you, this repair service offered is simple, fast and cost-effective.
IE3 / IE4 AC motors
You can also purchase premium-quality IE3 / IE4 energy-saving motors. The most important efficiency classes are IE1, IE2, IE3 and IE4. The legal requirements of minimum efficiency are as follows:
- since 16 June 2011, the minimum efficiency of motors (0.75 kW - 375 kW) must be in compliance with the efficiency IE2.
- since 1 January 2015, the minimum efficiency of motors (7.5 kW - 375 kW) must be in compliance with the efficiency IE2, or the motors must be operated as IE3 with frequency inverter.
- since 1 January 2017, the minimum efficiency of motors (0.75 kW - 375 kW must be in compliance with the efficiency IE2, or the motors must be operated as IE3 with frequency inverter. Legal requirements and information about this can be found on the pages of the ZVEI (German umbrella organization of the electrical and electronic industry).
Three-phase motors with a variable number of poles
In addition to standard motors, also motors with a variable number of poles are offered. Our motors ex stock are available with two speeds, with a constant torque, in delta connection / double Y connection, at a rated voltage of 400 V, 50 Hz. Moreover, they come in various designs i.e. in sizes of 71, 80, 90, 100, 112 and 132 and in different construction types such as B3, B5, B35, B14, B34, V1 and V6. Altering the speed of the motors is effected by varying the number of poles i.e. 2/4 (3000/1500 rpm), 4/8 (1500/750 rpm), 4/6 (1500/750 rpm), 6/8 (1000/750 rpm) and 2/8 (3000/750 rpm). Motor powers range from 0.08 kW to 5.5 kW. Higher powers, motors with three speeds, with a torque square function or Dahlander motors are available on request.
Modified electric motors
In many cases, standard motors are needed to be designed to match customer's individual requirements. With our qualified personnel, our large stock of motors and our own final assembly, we are a perfect partner for businesses that need external expertise in a large spectrum of issues – whether it is a specific brake motor, circular saw motor, electric motor with frequency inverter, special shaft, special motor flange, modified terminal box, extended fan hood, motors without fan, in 290/500V, progressive construction type, special motor winding or an electric motor with a predefined degree of protection such as IP54, IP55, IP56 or IP65.
