No, power is torque times speed, so a motor with same torque regardless of speed (i.e. typical servo motor) would have linearly increasing power output with increasing speed.
In SI units, P [W] = M [Nm] * omega [rad/s]. Written out: Power [in watts] equals Torque [in newton meters] times angular velocity [in radians per second].
