Internal Product Review

The MT1506B1-E2C1 is a Kollmorgen M Goldline servo motor with 0.65 kW rated power and 6000 rpm maximum operating speed. Continuous torque performance is especially strong, delivering 1.474 N-m stall torque at 25°C and 4.67 N-m peak torque for dynamic motion profiles. A 5.86 ARMS continuous line current supports efficient drive matching, making the motor a very capable choice for responsive servo applications.

Product Description:

The MT1506B1-E2C1 is a brushless servo motor produced by Kollmorgen for the M Goldline Servo Motors series. It is built for closed-loop position and velocity control in industrial automation applications that require compact torque density and rapid acceleration. When paired with a digital drive, the permanent-magnet motor converts electrical power into controlled mechanical rotation for packaging equipment, electronics assembly systems, and similar motion modules. Its brushless design supports responsive operation while eliminating the mechanical wear associated with motor brushes.

The motor has a back electromotive force of 14.5 V RMS/krpm, which is the terminal voltage generated for every thousand revolutions per minute of shaft speed. The connected drive must have a voltage rating suitable for this generated voltage across the intended operating range. At a winding temperature of 25 °C, the motor provides continuous stall torque of 1.474 N-m while drawing a steady phase current of 5.86 A RMS. These values establish the thermal and magnetic limits for holding a static load without overheating the windings. The motor can reach a maximum mechanical speed of 6000 rpm, allowing direct coupling to high-speed belts or suitable gear stages. Its rated power output is 0.65 kW, indicating the sustainable mechanical work rate at the rated operating point.

The motor has a phase inductance of 3.7 mH, which affects current rise time and the achievable servo-control bandwidth. It can produce a peak torque of 4.67 N-m for rapid indexing, acceleration, or brief increases in mechanical load. This peak value is substantially higher than the continuous stall torque, but it is intended for short-duration operation rather than sustained loading. The winding has a thermal time constant of 24 minutes, indicating how quickly its temperature approaches a steady operating level after the load changes. The unit weighs 1.9 kg without a holding brake, helping limit the additional mass placed on lightweight moving axes. Its low weight also reduces the structural load imposed on compact positioning assemblies without changing the available motor torque.
