MENZEL Elektromotoren – History

1927 At the age of 23, Kurt Menzel forms the company “Kurt Menzel” in Berlin.

1939-1945 During World War II, the warehouses, shops and offices are hit eleven times by aerial bombardment, sustaining severe damage.

1948 Gisela Menzel enters the family business.

1958 Acquisition of a 10,000 m² plot in Berlin-Tiergarten, and relocation of the company.

1959-1962 Construction and expansion of warehouses and shops

1975 Having completed his studies as a certified engineer, Kurt Menzel Junior takes over the Sales Department.

1984 After the passing of Kurt Menzel Senior, the business is converted into a limited liability company, Menzel Elektromotoren GmbH.

1993 In response to the rapid expansion of the business, an off-site warehouse of 2,000 m² is rented in Lauchhammer (Brandenburg).

1995 Acquisition of a 6,000 m² lot in Freienhufen (Brandenburg), and relocation of the off-site warehouse to this lot.

2001 Another off-site warehouse of about 7,000 m² is acquired in Brieske (Brandenburg) to increase the storage capacity.

2005 Mathis Menzel, certified engineer, enters the company, having completed his studies in electric engineering and gathered first professional experience in England, France, and Spain. His sphere of ownership is international sales.

2007 Mathis Menzel, cert. en., becomes a member of the management.

2007 In order to shorten the response time, a storage facility for new high-voltage motors is set up on the site of a logistics provider. Thus, the Menzel high-voltage series is now available with comprehensive logistics services and very quick response times.

2007 At the Berlin location, capacities are expanded on a major scale in order to meet the rising demand. Among other things, a new assembly line and two new crane systems are set up.

2007 Sales activities in the high voltage technology segment are pooled at the Hanover branch office.

2008 Menzel Skandinavien AB is formed in order to provide faster and better key account management for customers in the Scandinavian countries.

2009 Menzel France SARL and Menzel Great Britain Ltd. were founded in order to serve the local markets quicker and to provide personal support from that time on.

2010 New frequency converter type series and soft starters supplement the product range.

2012 The Berlin location was modernized and further expanded with a highly modern paintshop.

2012 Menzel Italia S.r.l. was founded and from now on will support our Italian customers from the Milan office.

2012 At the Berlin location, a second highly-modern test field was put into operation. With its 2,300 kVA, 400-13,200 V and converters up to 120 Hz, it is now also available for external customer to test their motors.

Be it a high- or low-voltage motor, direct current motor, slip ring or squirrel cage motor, frequency inverter or any other …

Since 1927, we have been producing and delivering all types and sizes of industrial motors world-wide – from standard low voltage motors up to customized items for individual projects with up to 20,000 kW output.

The technical options are versatile, our stocks of over 20,000 motors, generators and transformers are huge – take a look at our product portfolio or simply send us a direct request. We will then prepare an interesting offer immediately.

Beyond the delivery of our standard series, we also produce electric motors in custom versions in every imaginable type according to the specifications and requirements of our customers, as individual items for special applications as well as a reserve or replacement that is mechanically or electrically interchangeable with existing motors.

Among our extensive product range you will find:

Squirrel cage and slip ring motors up to 20,000 kW

Low voltage motors starting from 0,75 kW

Direct current motors up to 2,000 kW
