FAQ
Q1. What information is required to select the GMP36MBL3640 brushless DC gear motor?
Please provide the operating voltage, target output speed, continuous and peak torque, installation space, output shaft requirements, duty cycle, control method, feedback requirements, ambient temperature, target lifetime, and annual quantity. The gear ratio should be selected together with the required speed and load rather than from ratio alone.
Q2. Does this BLDC gear motor include a driver?
Yes. The supplied product data identifies the BL3640SG as a brushless DC gear motor with a built-in driver. However, the external control-signal definitions and electrical logic are not specified in the supplied material, so the control interface should be confirmed before system integration.
Q3. What gear ratios and voltages are available?
The supplied reference table covers 12 VDC, 24 VDC, and 36 VDC configurations with ratios of 1:5, 1:14, 1:27, 1:51, 1:71, 1:100, 1:189, 1:369, 1:516, and 1:977. Final availability should be confirmed for the exact BL3640SG configuration.
Q4. What control interface is available for the GMP36MBL3640?
The supplied data confirms a built-in driver, but it does not define PWM, direction, speed-feedback, connector pinout, or logic-level specifications. These interface details should be confirmed during engineering evaluation before the customer controller is finalized.
Q5. Can the shaft, ratio, wiring, or connector be customized?
Customization can be evaluated based on the application. Please provide the required shaft drawing, installation dimensions, target speed and torque, wire length, connector specification, control interface, duty cycle, and annual demand so the engineering team can confirm feasibility.
