R911291957
Bosch Rexroth Indramat's R911291957 (MHD115C-024-PP0-LA) is a high-performance synchronous motor with a time constant of 100 minutes and a natural convection cooling style. It's required to be operated with a drive controller and is adept in functioning under adverse environmental conditions. This motor offers high dynamism, showcasing a torque to inertia mass ratio. While the electrical connection points should not be touched when ON, it provides quick startup due to the data memory in the encoder, allowing for both horizontal and vertical installations.
The motor employs both electric and electronic commutation and indicates key technical attributes including a torque constant of 1.65Nm/A, voltage constant of 150V/1000min-1, and winding resistance of 0.185 at 20°C. Designed with a low inertia mass, the motor can use its peak torque over a wide speed range. Despite not being suitable for extreme temperature variations, the device handles a storage and transportation temperature range from -20°C to 80°C. The motor also features Class F insulation according to DIN VDE 0530 Part 1 regulations and a robust prime black RAL 9005 varnish resistant to diluted lyes, acids, chalking, weather, and color change. Note that when installed vertically, no fluid should accumulate on its output shaft.
