Servo Dynamics MTS30M4-38 servo motor

1、 Basic parameters

Voltage and speed

Rated voltage: 140V (some data mention 220V, which may be due to differences in model or configuration, and the actual product identification should prevail).

No load speed gradient: 38V/1000RPM (i.e. for every 38V increase in voltage, the speed increases by 1000 revolutions).

Maximum speed: 3700 RPM (unloaded), meeting the requirements of high-speed motion control.

Rated speed: Some data mention 450 RPM (which may correspond to specific loads or configurations, and needs to be confirmed based on the application scenario).

Torque performance

Continuous stall torque (natural cooling): 26 lb in (approximately 3.0 Nm), suitable for continuous load scenarios.

Continuous stall torque (fan cooling): 49 lb in (approximately 5.5 Nm), with external cooling to enhance sustained output capability.

Peak torque: 124 lb in (approximately 14 Nm), supporting short-term high load breakthrough.

Torque constant (KT): 0.35 Nm/Amp (3.1 lb in/Amp), reflecting the conversion efficiency between current and torque.

Electrical Characteristics

Continuous stall current (natural cooling): 8.6 Amps, needs to be matched with driver current capacity.

Peak current: 47 Amps (corresponding to peak torque), the driver needs to support instantaneous high current output.

Winding resistance (excluding brushes): 0.82 Ohms, affecting motor efficiency and heat generation.

Inductance: 6.5 mH, affecting current response speed and control accuracy.

mechanical parameters

Shaft diameter: 1.87 inches (47.5mm), shaft end diameter 5/8 inches (15.875mm), key width 1.5 inches (38.1mm), compatible with standard couplings or transmission components.

Number of poles: 2 poles, simplifying the structure and improving speed stability.

Moment of inertia: 0.0017 Kg ² (0.015 lb in · sec ²), affecting dynamic response speed.

Weight: 7.3 Kg (16 lb), considering the load-bearing capacity of the installation structure.

thermal management

Insulation level: Class F, allowing a maximum winding temperature of 155 ° C and an upper limit of ambient temperature of 40 ° C (104 ° F).

Thermal time constant: 50 minutes, reflecting the motor's heat dissipation capability.

Mechanical time constant: 15 milliseconds, representing the acceleration ability of the motor from rest to rated speed.

2、 Core Features

Encoder integration

Standard configuration of 1000 line encoder, providing high-resolution position feedback, supporting closed-loop control, improving positioning accuracy and repeatability.

Cooling design

Supports two modes: natural cooling and fan cooling. Fan cooling can significantly improve continuous torque output (from 3.0 Nm to 5.5 Nm), adapting to different load intensity requirements.

dynamics

Theoretical acceleration (peak torque): 8200 Rad/Sec ², supporting rapid start stop and direction switching.

Mechanical static friction torque: 0.15 Nm (1.3 lb in), low friction design reduces starting torque fluctuations.

3、 Application scenarios

High speed positioning system

The combination of 3700 RPM maximum speed and 1000 line encoder is suitable for automation equipment that requires high precision and high speed, such as CNC machining centers, robot joints, etc.

Continuous operation under medium to high load

Under the cooling mode of the fan, a continuous torque of 5.5 Nm can drive loads such as conveyor belts and indexing plates that require long-term stable operation.

Short term high load breakthrough

14 Nm peak torque and 47 Amps peak current, supporting scenarios such as stamping machines and injection molding machines that require instantaneous high torque.
