Joliet Equipment Corporation is a distributor that specializes in large industrial motors of up to 30,000 HP.  They represent brands, such as  ABB, WEG, Hitachi, Baldor, Siemens, GE and Leeson. Joliet has available a line of motors for mud pump and rotary table applications. Amongst the product selection, the Joliet C75YZB Series of wound DC Hi-torque drilling motors feature continuous rating for applications of 1085 HP, continuous rating at 750 VDC, 1150 Amps, 965 RPM, and intermittent rating for applications of 1320 HP.

Kollmorgen produces permanent magnet and brushless motors. Line includes direct drive DC torque motors and permanent magnet type. Direct drivetorque motors features high stall torque for positioning systems, high torque at low speeds for speed control systems, optimum torque at high speed for positioning, rate, or tensioning systems, diameter range from 1.13 to 32 in. PMDC motors include low voltage motors, explosion proof motors, 90 and 180 VDC motors, and "sealed tight food" washdown motors with a HP range from 1/8 to 3. Brushless motors include conventional rotary servo motors, direct drive rotary motors, and direct drive linear motors with high torque/inertia ratio, and high speeds up to 8,000 rpm or 70,000 rpm for special designs.

SL-MTI offers brushed DC motors, with maximum continuous stall torque of 0.55 to 14.11 oz-in, alnico and rare earth magnet materials, high temperature insulation for environments 180C or higher, high altitude operation component design, and more for small radar systems, fuel monitoring systems, autopilot mechanisms, navigation devices, and more.

Allied Motion makes right angle gearmotors, DC parallel-shaft gearmotors, brushless DC motors, and permanent magnet DC motors. Their Endurance 30 PJ series PMDC motors feature a 5/16-inch cold rolled steel shaft, Class "B" winding, IP54 protection level, continuous speed up to 3600rpm, rugged zinc die-cast end frames, and more.

Axsys Technologies supplies a line of brushless and brush DC torque motors.
