Malloy Electric & Bearing Supply was started in 1945 by Emmett and Mary Malloy. It was located across from the Post Office in downtown Sioux Falls, South Dakota. Their main capabilities were in the Motor Repair Shop and Electric Construction Shop. They built a new shop at 16th and Cliff Avenue in Sioux Falls in the early 1960’s. Malloy employed about 6 people then.

On March 1,1971, Garry and Dianne Jacobson purchased Malloy Electric. They built a new facility at 809 West Russell Avenue in Sioux Falls, South Dakota, and moved in 1974. The sales area was expanded to incorporate the retail sales of motors, electrical equipment, and power transmission equipment. The Machine Shop was added in October of 1978.


A branch facility, located in Sioux City, Iowa was incorporated to the Malloy family in February of 1986. In December of 1986, an Electronic Shop was added to both facilities. The facility in Sioux City is 17,000 square feet, offering a Motor Repair Shop, Machine Shop, and Sales facility. In 1995, a 3,000 square foot warehouse was added to increase inventory capacity.

In 2001, Thorp Electric in Sioux City, Iowa was purchased and added to the Malloy family of service shops. Thorp is a 28,000 square foot service center capable of rebuilding the largest sizes of electric motors and industrial equipment.


In August 2008, a branch office was opened in Omaha, Nebraska to better serve southern Iowa and eastern Nebraska. In 2009, Malloy Electric proudly announced completion of a new 75,000 square foot "state of the art" industrial service center located on 11 acres of land at Exit 1 and I-29 in Dakota Dunes, SD. This allowed Malloy to consolidate its two locations in Sioux City into one. The new facility houses Malloy's inside technical support, outside sales, motor repair center for motors thru 8,000 HP, machine shop, eletronic service department, engineering services, office, and large warehouse.

The Malloy facility in Sioux Falls is a 36,000 square foot facility. Additions were built on in 1976, 1980, 1989, and 2000. A 10,000 square foot warehouse was added across the street in 2008. Today, Malloy’s employs about 130 people and maintains three facilities. A strong commitment to customer service and technical improvements has made Malloy a key player in the motor, control, and power transmission industry.
