DC Servo motors CML Series

Product catalog summary

Overview: The CML Series of DC Servo Motors are characterized by their small dimensions, radial magnetic flux, high performance, and square format. These motors are designed for applications requiring compact and efficient solutions.

Performance Curves: The performance curves illustrate the relationship between speed (rpm) and torque (Nm) for different models (CML-30, CML-50, CML-60). The curves indicate that as speed increases, torque decreases, which is typical for servo motors.

Encoder Specifications: The encoders produce a square waveform with 1000 pulses per revolution (ppr). They include channels A, B, Z, and their complements, as well as U, V, W channels. The encoders operate with a supply voltage of 5VDC ± 10% and have a frequency response of 200 kHz, suitable for temperatures ranging from -40°C to +120°C.

Tachometer Specifications: The tachometer has a voltage constant of 10 V/krpm with a ripple of less than 1.5% at 1000 rpm. It maintains linearity within 0.1% at 6000 rpm and has a reversing error of 0.12%. The temperature coefficient is 0.03%/°C, and the rotor inertia is 0.004 kg m² x 10^-3.

Technical Specifications: All characteristics are measured at 25°C ambient temperature. Key parameters include rated speed, voltage, current, output power, torque, and maximum speed. The motors have different specifications based on the model:

CML-30: Rated speed of 3000 rpm, voltage of 24V, current of 2.1A, and output power of 25W.
CML-50: Rated speed of 3000 rpm, voltage of 34V, current of 2.7A, and output power of 63W.
CML-60: Rated speed of 3000 rpm, voltage of 24V, current of 3.9A, and output power of 47W.

Additional specifications include EMF constant, torque constant, friction torque, damping constant, terminal resistance, armature inductance, rotor inertia, mechanical and electrical time constants, thermal time constant, thermal resistance, mass, radial load, and axial load. These parameters are crucial for understanding the motor's performance and suitability for specific applications.
