Low-voltage induction (squirrel-cage) electric motors
represent the fundamental part of firm assortment. Motors with single or three phase supply in the range of 220V – 690V, covering the power spectrum of 0,06kW – 1250kW, are considered to be low-voltage motors.

Standard energy-saving motors (increased efficiency)
Are the mostly used electric motors for all kinds of prevailing applications, running in common working environment (with exception of explosion or inflammation hazard).
This category covers mainly series 1LA7, 1LG4, 1LE1 and derived, with power scale from 0,04 to 200kW. Both bipolar and four-polar motors are certified as EFF2 (higher efficiency) according to CEMEP, newly marked as IE1.
The key advantages are as follows:
-
Operation energy savings
-
The broadest configuration possibilities – installation of modular bodies (electromagnetic brakes, ventilation units, IR, heat protection etc), various mechanical modifications (alteration of shaft shape, various positions of junction boxes, various bearings types, etc.)
-
Very high availability (the major part of units in KVELB stock).
-
Standardized dimensions ensuring compatibility with other brand products
-
Purchase and configurations possible in our e-shop
High efficiency motors
Are electric motors used for common applications, with high operation energy savings. Motors designed for these customers who are aware of the fact that primary drive costs are usually not relevant sums comparing the total drive cost.
This category covers mainly 1LA9, 1LG6, 1LE1 and derived, with power scale from 0,06 to 200kW. Both bipolar and four-polar motors are certified as EFF2 (higher efficiency) according to CEMEP, newly marked as IE1.
Key features are as follows:
-
High operation energy savings compensate higher primary (acquisition) price
-
Available in similar design scale and mechanical modifications as in standard motors case
-
Suitable also for running in generator regime (induction generators for small hydraulic power plants, wind power plants, etc).
-
Standardized dimensions ensuring compatibility with other brand products
-
Currently, the purchase is not possible online, however we would be glad to prepare any offer for you
Motors with increased power
Are electric motors used for common applications, with the best load/size (weight) ratio. These motors are destined for such case of application where maximum load is necessary at the smallest drive dimension (weight) or in case load increase of already applied drive without mechanical modification necessity.
This category covers mainly 1LA9, 1LG4, 1LE1 and derived, with power scale from 0,14 to 200kW.
Key features are as follows:
-
High load at small size and lower motor height
-
Available in similar design scale and mechanical modifications as in standard motors case
-
Running with frequency converter only for limited scale of modifications, details on request.
-
Standardized dimensions ensuring compatibility with other brand products
-
The majority of products available in our e-shop
-
Quite good availability (the frequent units in KVELB stock).
Explosion proof motors:
are electric motors for running in environment with higher danger of inflammation caused by flammable vapours, gases and combustible dust.
Power scale from 0,06 to 132kW, 900kW on demand
This category covers following series:
Zone 1:
1MJ6, 1MJ7 ... motors with protection rate of EEx de II or EEx d II
AOM / AVM / AKM ... motors with protection rate EEx d II or EEx d I (for pits)
1MA7 a 1MA6 ... motors with protection rate EEx e II
Zone 2:
1LA7, 1LG4 and other basic series either with option M72 (mains supply) or with option M73 (frequenter-powered)
Zone 21:
1LA7, 1LG4 and other basic series either with option M34 (mains supply) or with option M38 (frequenter-powered)
Zone 22:
1LA7, 1LG4 and other basic series either with option M35 (mains supply) or with option M39 (frequenter-powered)
General features:
-
In a frequenter-powered case, special modification or special outfit is needed
-
Limited possibilities of configuration (usually modular body is not applicable, mechanical modifications are limited)
-
To each motor, ATEX certificate is supplemented
-
Standardized dimensions ensuring compatibility with other brand products
-
The majority of products available in our e-shop
-
Quite good availability (the frequent units in KVELB stock).
Bigger Low-Voltage Motors – with load range from 145kW, from axial size of 315
Electric motor designated for low voltage applications, requiring high power output.
This category covers mainly 1LA8, 1PQ8, 1LL8 and derived, with power scale from 145 to 1250kW.
Key features
-
Various modifications of winding used for mains supply or frequenter supply
-
Wide range of designs and mechanical modifications are available
-
Standardized dimensions ensuring compatibility with other brand products
-
Currently, the purchase is not possible online, however we would be glad to prepare any offer for you
Single-phase Induction Motors
are electric motors designated for standard applications, “emergency” choice when three-phase power supply is not available.
Series 1LF7 and power outputs up to 3kW are covered.
-
Modifications with running capacitor for easy starting
-
Modifications with running and starting capacitor for heavier starting
-
Installation of heat protection possible, other configurations are limited
-
Mechanical modifications also possible only in a limited range (various bearing kinds, various positions of terminal board, modifications of shaft shape,..)
-
Available in our e-shop
