Internal Product Review
The MTC726B2-S1C1 is a Kollmorgen MTC servo motor with strong dynamic potential for demanding motion systems. Continuous stall torque of 50.4 N-m and peak torque of 152.3 N-m give the unit confident low-speed holding and excellent overload capability. A 24 VDC brake and 6383 rad/s2 maximum theoretical acceleration make this model a very capable choice for precise, high-response servo applications.

Product Description:
The MTC726B2-S1C1 is a brushless permanent-magnet servo motor manufactured by Kollmorgen for the MTC Servo Motors series. It converts controlled stator currents into precisely regulated shaft torque, enabling coordinated positioning and velocity control on packaging lines, gantry axes, and machine-tool spindles. The design supplies mechanical power while the paired drive manages speed loops and trajectory generation in automated cells.
The motor’s electrical constants determine how it must be driven. A back EMF of 166.5 VRMS/krpm indicates the voltage that the drive will receive per 1,000 rpm, helping establish suitable power-stage ratings. Under continuous duty, the motor accepts 18.3 ARMS of line current to sustain a shaft load of 50.4 N-m. Its torque sensitivity of 2.75 N-m/ARMS links commanded current directly to output torque. Transient demands are supported by a peak current capacity of 64.7 ARMS, which produces 152.3 N-m of torque. These dynamic bursts, together with a maximum theoretical acceleration of 6,383 rad/s², support rapid indexing moves when position errors must be corrected quickly.
The rotor inertia of 0.0239 kg·m² balances responsiveness with load matching, and static friction is limited to 0.584 N-m so small commands can produce motion without hunting. Eight magnetic poles synchronize with high-resolution feedback devices, while the stall torque at 25 °C is 53.7 N-m. The windings have 0.553 Ω of DC resistance and 18.5 mH of inductance, which the drive uses for current-loop modeling. A brake rated at 24 VDC secures the shaft when power is removed. The thermal time constant of 72 minutes slows the temperature rise during extended operating cycles. The housing has an overall length of 300.5 mm, providing an installation reference for available machine space and coupling alignment.
